This commit changes the Arduino board identifiers to correspond to their
official names. This helps to identify boards at runtime. At the moment
the Arduino Portenta H7 is reported as PORTENTA which is unfortunate as now
there is another Portenta board (Portenta C33) supported in MicroPython.
Also made the other identifiers for flash and network name consistent,
removed the incorrectly used MICROPY_PY_SYS_PLATFORM identifiers, and added
missing MICROPY_PY_NETWORK_HOSTNAME_DEFAULT identifiers.
Boards affected:
- stm32: ARDUINO_PORTENTA_H7, ARDUINO_GIGA, ARDUINO_NICLA_VISION
- renesas-ra: ARDUINO_PORTENTA_C33
- esp32: ARDUINO_NANO_ESP32
- rp2: ARDUINO_NANO_RP2040_CONNECT

Functionality and code size don't really change, but removes port-specific

(The MSC implemented in shared/tinyusb depends on some functions in the
pico-sdk, so this change doesn't make this available for samd.)

See the commit a00c9d56db for a detailed description of the problem, a
regression introduced in 26d503298.
Same approach here as the linked fix for rp2 (applied unconditionally here
as this port only supports USB-CDC for stdin/stdout).

The recent change in bcbdee235719d459a4cd60d51021454fba54cd0f means that
TinyUSB can no longer be run from within a soft (or hard) IRQ handler, ie
when the scheduler is locked. That means that Python code that calls
`print(...)` from within a scheduled function may block indefinitely if the
USB CDC buffers are full.
This commit fixes that problem by explicitly running the TinyUSB stack when
waiting within stdio tx/rx functions.

Similar to 3883f29485fad21105f6f965d56bfec842b8cfbb where this change was
implemented for threads: when the Bluetooth IRQ handler is called the
thread state is not not zero-initialized and thus we need to manually set
this to NULL.

If you have a variable frequency and pulse width, and you want to optimize
pulse resolution, then you must do a calculation beforehand to ensure you
normalize the array to keep all list values within bound. That calculation
requires RMT.source_freq(), RMT.clock_div(), and this 32767 constant.

To create an esp32.RMT() instance with an optimum (i.e. highest resolution)
clock_div is currently awkward because you need to know the source clock
frequency to calculate the best clock_div, but unfortunately that is only
currently available as an source_freq() method on the instance after you
have already created it. So RMT.source_freq() should really be a class
method, not an instance method. This change is backwards compatible for
existing code because you can still reference that function from an
instance, or now also, from the class.

Previously the TinyUSB task was run in the ISR immediately after the
interrupt handler. This approach gives very similar performance (no change
in CDC throughput tests) but reduces the amount of time spent in the ISR,
and allows TinyUSB callbacks to run in thread mode.

This change:
- Has a small code size reduction.
- Should slightly improve overall performance. The old hook code
seemed to use between 0.1% and 1.6% of the total CPU time doing no-op
calls even when no USB work was required.
- USB performance is mostly the same, there is a small increase in
latency for some workloads that seems to because sometimes the hook
usbd_task() is called at the right time to line up with the next USB host
request. This only happened semi-randomly due to the timing of the hook.
Improving the wakeup latency by switching rp2 to tickless WFE allows the
usbd_task() to run in time for the next USB host request almost always,
improving performance and more than offsetting this impact.

dcd_event_handler() is called from the IRQ when a new DCD event is queued
for processing by the TinyUSB thread mode task. This lets us queue the
handler to run immediately when MicroPython resumes.
Currently this relies on a linker --wrap hack to work, but a PR has been
submitted to TinyUSB to allow the function to be called inline from
dcd_event_handler() itself.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. At this stage only esp32 implements
this class, so the code for the bindings comes from that port.
The documentation is also updated to reflect the esp32's behaviour of
ADCBlock.connect().

This handles the case where an empty bytes/bytearray/str could pass in
NULL as the str argument (with length zero). This would result in UB in
strncmp. Even though our bare-metal implementation of strncmp handles
this, best to avoid it for when we're using system strncmp.

C99 says that strncmp has UB for either string being NULL, so the
current behavior is technically correct, but it's an easy fix to handle
this case correctly.
7.1.4: "unless explicitly stated otherwise in the detailed
description... if an argument to a function has ...null pointer.. the
behavior is undefined".
7.21.1: "Unless explicitly stated otherwise in the description of a
particular function in this subclause, pointer arguments on such a call
shall still have valid values, as described in 7.1.4".
Also make the same change for the minimal version in bare-arm/lib.c.

Remove port-specific test directories and excluded tests from
tinytest-codegen, and let it read said information from an external file.
This way tinytest-codegen is not limited to always generate tests for the
`qemu-arm` target.
This allows having port-specific test directory and excluded tests for more
than one QEMU bare-metal target.
The `qemu-arm` port Makefile was modified to work with the generator
changes and a tests profile file was added to said port.

The main motivation for doing this was to reduce the latency when the
system is woken by a USB interrupt. The best_effort_wfe_or_timeout()
function calls into the pico-sdk dynamic timer framework which sets up a
new dynamic timer instance each time, and then has to tear it down before
continuing after a WFE.
Testing Python interrupt latency, it seems to be improved by about 12us
(from average of 46us to 34us running a Pin IRQ). C-based "scheduled
nodes" should see even lower latency.

The FIFO reports not only the bytes read, but also 4 error bits. These were
not checked, leading to NUL value read in case of break and possible
garbage bytes being written on parity/framing error.
This patch addresses the issue that NUL bytes are incorrectly read on
break, and at least provides the boilerplate code and comments for error
handling, that may be implemented in the future.

Update rtc, machine and powerctrl drivers to support STM32H5 sleep
modes. This makes RTC alarm wakeup working from lightsleep() and
deepsleep().
Changes:
- Determine start reason for machine.reset_cause() in modmachine.c.
- Add proper interrupt clear code in rtc.c.
- Add wakeup functionality in powerctrl_enter_stop_mode(). Remember
and restore voltage scaling level. Restart HSI48 if it was on before
entering sleep mode.
- Clear DBGMCU_CR in SystemClock_Config() as for other variants.
Otherwise debug flags prevent entering sleep mode.
Implementation Notes:
- rtc.c: EXTI_RTSTR1 bits are not present for H5. Code sequence from
G0/G4/L4/WB/WL would be invalid. RTSTR is only defined for external
(GPIO) interrupts. Maybe this is also true for other STM32 variants.
- powerctrl_enter_stop_mode() uses complicated, nested conditionals
to select STM32 variants. To make code slightly better readable,
comment have been added. A non-nested, #if/#elif sequence would
make the code more readable. I leave this to the original authors.
