Use new function mp_obj_new_str_from_cstr() where appropriate. It

There were lots of places where this pattern was duplicated, to convert a
standard C string to a MicroPython string:
x = mp_obj_new_str(s, strlen(s));
This commit provides a simpler method that removes this code duplication:
x = mp_obj_new_str_from_cstr(s);
This gives clearer, and probably smaller, code.

The change closes the gap in the API when an integer is used as Pin
reference. With the change, e.g. ADC(26), ADC(Pin(26)) and ADC("GP26")
behave identically and the GPIO is initialised in ACD/high-Z mode.
Only when using ADC channel numbers 0-3 are the corresponding GPIO left
uninitialised, and then the user is responsible for configuring the GPIO.

There are three changes here:
- Fix `rp2_pio_print` to use `pio_get_index()` too, since it had its own
copy of the ternary expression.
- Remove a ternary from `rp2_pio_state_machine` and calculate it from
`pio_get_index`.
- Remove a ternary on `GPIO_FUNC_PIO0` vs `GPIO_FUNC_PIO1`. These
constants are sequentially ordered so we can calculate them too.

The `PIO_NUM` macro was defined when `rp2_pio.c` was first conceived.
There's now a Pico SDK function for this, `pio_get_index()`, which is
already used in some parts of the code.
This commit removes `PIO_NUM` in favour of using `pio_get_index()`
everywhere.

Enable support for cipher suites like
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, as suggested in
https://github.com/micropython/micropython/issues/14204#issuecomment-2024366349
and https://github.com/micropython/micropython/issues/10485#issuecomment-1396426824
Tests have been run on the top 500 domains from moz.com. Without this
patch, 155 out of 500 fail to connect because of TLS issues. This patch
fixes them all. And it seems all existing mbedtls flags are needed to get
good coverage of those top 500 domains.
The `ssl_poll.py` test has the cipher bits increased from 512 to 1024 in
its test key/cert so that it can work with ECDHE-RSA which is now the
chosen cipher.

Before this change, long/mpz ints propagated into all future calculations,
even if their value could fit in a small-int object. With this change, the
result of a big-int binary op will now be converted to a small-int object
if the value fits in a small-int.
For example, a relatively common operation like `x = a * b // c` where
a,b,c all small ints would always result in a long/mpz int, even if it
didn't need to, and then this would impact all future calculations with
x.
This adds +24 bytes on PYBV11 but avoids heap allocations and potential
surprises (e.g. `big-big` is now a small `0`, and can safely be accessed
with MP_OBJ_SMALL_INT_VALUE).
Performance tests are unchanged on PYBV10, except for `bm_pidigits.py`
which makes heavy use of big-ints and gains about 8% in speed.
Unix coverage tests have been updated to cover mpz code that is now
unreachable by normal Python code (removing the unreachable code would lead
to some surprising gaps in the internal C functions and the functionality
may be needed in the future, so it is kept because it has minimal
overhead).

This commit changes a few code sequences to use more compressed opcodes
where possible. The sequences in question are the ones that show up the
most in the test suite and require the least amount of code changes, namely
short offset loads from memory to RET/ARG registers, indirect calls through
the function table, register-based jumps, locals' offset calculation,
reg-is-null jumps, and register comparisons.
There are no speed losses or gains from these changes, but there is an
average 15-20% generated code size reduction.

Pico SDK defines `__dsb()` and `__sev()` so use those instead of the CMSIS
equivalents. This matches the use of `__wfi()` in lieu of `__WFI()` and
lowers the dependency on CMSIS headers.
And then, move the include of "RP2040.h" from the widely-included
"mphalport.h" to specific source files that need this header, to keep its
inclusion contained.

It looks like the variants for this board were never being built properly,
because the auto-build system used the variant name from `board.json` which
did not match the variant names in the original `mpconfigboard.mk`. Eg
`FLASH_2MB` in `board.json` but `FLASH_2M` in `mpconfigboard.mk`.
This mistake is apparent since 5dff78f38edc0354e854e6c73af61c5064afe9d3,
which made it a build error to specify an invalid variant.
Fix this by using the correct variant names in `board.json`.

In JavaScript when accessing an attribute such as `obj.attr` a value of
`undefined` is returned if the attribute does not exist. This is unlike
Python semantics where an `AttributeError` is raised. Furthermore, in some
cases in JavaScript (eg a Proxy instance) `attr in obj` can return false
yet `obj.attr` is still valid and returns something other than `undefined`.
So the source of truth for whether a JavaScript attribute exists is to just
right away attempt `obj.attr`.
To more closely match these JavaScript semantics when proxying a JavaScript
object through to Python, change the attribute lookup logic on a `JsProxy`
so that it immediately attempts `obj.attr` instead of first testing if the
attribute exists via `attr in obj`.
This allows JavaScript objects which dynamically create attributes to work
correctly on the Python side, with both `obj.attr` and `obj["attr"]`. Note
that `obj["attr"]` already works in all cases because it immediately does
the subscript access without first testing if the attribute exists.
As a benefit, this new behaviour matches the Pyodide behaviour.

`mpconfigvariant_VARIANT.mk` file associated with it. The base variant

This commit reworks board variants on the esp32 port. It's a simple change
that moves the board variant configuration from an "if" statement within
`mpconfigboard.cmake` into separate files for each variant, with the name
of the variant encoded in the filename: `mpconfigvariant_VARIANT.cmake`.
Optionally, the base variant can have its own options in
`mpconfigvariant.cmake` (this is an optional file, but all other variants
of the base must have a corresponding mpconfigvariant file).
There are two benefits to this:
- The build system now gives an error if the variant that you specified
doesn't exist (because the mpconfigvariant file must exist with the
variant name you specify).
- No more error-prone if-logic needed in the .cmake files.
The way to build a variant is unchanged, still via:
$ make BOARD_VARIANT=VARIANT

Compiling using arm-none-eabi-gcc 14.1.0 with -O2 will give warnings about
possible overflow indexing extint arrays, such as `pyb_extint_callback`.
This is due to `machine_pin_obj_t.pin` having a bit-width of 5, and so a
possible value up to 31, which is usually larger than
`PYB_EXTI_NUM_VECTORS`.
To fix this, change `machine_pin_obj_t.pin` to a bit-width of 4. Only 4
bits are needed for ST MCUs, which have up to 16 pins per port.

The `mp_event_wait_ms()` function may return earlier than the requested
timeout, and if that happens repeatedly (eg due to lots of USB data and
IRQs) then the loop waiting for CDC TX FIFO space to become available may
exit much earlier than MICROPY_HW_USB_CDC_TX_TIMEOUT, even when there is
no space.
Fix this by using `mp_hal_ticks_ms()` to compute a more accurate timeout.

Follow-up to a84c7a0ed93, this commit works most of the time but has an
intermittent bug where USB doesn't resume as expected after waking from
light sleep.
Turns out waking calls clocks_init() which will re-initialise the USB PLL.
Most of the time this is OK but occasionally it seems like the clock
glitches the USB peripheral and it stops working until the next hard reset.
Adds a machine.lightsleep() test that consistently hangs in the first
two dozen iterations on rp2 without this fix. Passed over 100 times in a
row with this fix.
The test is currently rp2-only as it seems similar lightsleep USB issues
exist on other ports (both pyboard and ESP32-S3 native USB don't send any
data to the host after waking, until they receive something from the host
first.)

mp_thread_begin_atomic_section() is expected to be recursive (i.e. for
nested machine.disable_irq() calls, or if Python code calls disable_irq()
and then the Python runtime calls mp_handle_pending() which also enters an
atomic section to check the scheduler state).
On rp2 when not using core1 the atomic sections are recursive.
However when core1 was active (i.e. _thread) then there was a bug that
caused the core to live-lock if an atomic section recursed.
Adds a test case specifically for mutual exclusion and recursive atomic
sections when using two threads. Without this fix the test immediately
hangs on rp2.

Fixes and improvements to `int.to_bytes()` are:
- No longer overflows if byte size is 0 (closes #13041).
- Raises OverflowError in any case where number won't fit into byte length
(now matches CPython, previously MicroPython would return a truncated
bytes object).
- Document that `micropython int.to_bytes()` doesn't implement the optional
signed kwarg, but will behave as if `signed=True` when the integer is
negative (this is the current behaviour). Add tests for this also.
Requires changes for small ints, MPZ large ints, and "long long" large
ints.
Adds a new set of unit tests for ints between 32 and 64 bits to increase
coverage of "long long" large ints, which are otherwise untested.
Tested on unix port (64 bit small ints, MPZ long ints) and Zephyr STM32WB
board (32 bit small ints, long long large ints).

Prior to this fix the current working path in the remote VFS would always
be prepended to the requested path to get the full path, even if the
requested path was already absolute, ie starting with "/".
So `os.chdir("/remote/dir1")` would set the working path to "/dir1/", and
a subsequent call with an absolute path like `os.listdir("/remote/dir2")`
would try to list the directory "/dir1/dir2/".
Fixes issue #15308.

The code generating the entry to the finally handler of an async-with
statement was simply wrong for the case of the native emitter. Among other
things the layout of the stack was incorrect.
This is fixed by this commit. The setup of the async-with finally handler
is now put in a dedicated emit function, for both the bytecode and native
emitters to implement in their own way (the bytecode emitter is unchanged,
just factored to a function).
With this fix all of the async-with tests now work when using the native
emitter.
