Add native gchelper support for 64 bits RISC-V RV64I targets.
Now that RV64 is under CI, this also enables platform-specific ghelper
in the Unix port.
Also changes the data type holding the register contents to something more
appropriate, so in the remote eventuality somebody wants to use this with
RV128 all they have to do is update the `__riscv_xlen` check.

Updating a set must use `.update()` rather than `.add()`.
Also apply the same pattern to qemu-riscv to prevent the same issue when
directories/files are added to that port's `tests_profile.txt` file.

Finalisers that run during `gc_sweep_all()` may run native code, for
example if an open file is closed and the underlying block device is
implemented in native code, then the filesystem driver (eg FAT) may call
into the native code.
Therefore, native code must be freed after the call to `gc_sweep_all()`.
That can only be achieved if the GC heap is not used to store the list of
allocated native code blocks. Instead, this commit makes the native code
blocks a linked list.

The `emit_load_reg_with_object()` helper function will clobber `REG_TEMP0`.
This is currently OK on architectures where `REG_RET` and `REG_TEMP0` are
the same (all architectures except RV32), because all callers of
`emit_load_reg_with_object()` use either `REG_RET` or `REG_TEMP0` as the
destination register. But on RV32 these registers are different and so
when `REG_RET` is the destination, `REG_TEMP0` is clobbered, leading to
incorrectly generated machine code.
This commit fixes the issue simply by using `REG_TEMP0` as the destination
register for all uses of `emit_load_reg_with_object()`, and adds a comment
to make sure the caller of this function is careful.

Add `machine_i2s_deinit_all` to teardown any active I2S instances on soft
reset. Prior to this fix, code using I2S required a try/finally in order
to avoid a hard fault on soft reset.

This change has no impact on vanilla MicroPython builds, but is intended to
avoid RP2's PIO implementation from trampling PIO usage in USER_C_MODULES.
This is consistent with PIOs tracking of used state machines and managed
programs, and makes working with PIO in USER_C_MODULES much less of an
uphill battle.
Since PIO deinit runs before gc_sweep_all it's impossible to work around
this wrinkle otherwise. A module finalizer does not get the opportunity to
put the PIOs back into a state which wont crash rp2_pio_deinit.
Changes are:
- init: Avoid exclusive handlers being added to all PIOs and add them only
when needed.
- deinit: Only remove handlers we have set.
- rp2_pio_irq: Add the exlusive handler if needed.
- rp2_state_machine_irq: Add the exclusive handler if needed.

ESP-IDF driver always requires at least two DMA buffers, so ensure that's
the case.
Failures during initialisation were being lost because ESP_ERROR_CHECK is
configured as a no-op, so the failure was deferred until read() or write()
was called on the port. Raise an error from init, instead.

It seems like at some point Espressif NimBLE team changed
nimble_port_init and nimble_port_deinit to manage HCI init
internally:
https://github.com/espressif/esp-nimble/commit/f8a79b04c9743543b8959727d7
This change is included in all the IDF versions that MicroPython supports.
As a result, existing code that called esp_nimble_hci_deinit() explicitly
would trigger a use-after-free bug and heap corruption (specifically this
calls through to ble_transport_deinit() which calls os_mempool_free(). The
second time this writes out to a bunch of memory pools where the backing
buffers have already been freed.)
Symptoms were intermittent random crashes after de-activating Bluetooth
(running multi_bluetooth/ble_gatt_data_transfer.py could sometimes
reproduce). Setting Heap Poisoning to Comprehensive in menuconfig caused
the bug to be detected every time.

Swap FMC banks to remap the SDRAM bank1 address to 0x60000000. Arduino's
M4 firmware uses address 0x60000000 by default. When the elf loader tries
to load that it will fail because by default NOR/PSRAM is mapped at that
address, not SDRAM bank1. (Note that the region at 0xC0000000 has an XN
attribute by default, so switching the M4 firmware address will not work.)

The RV32 code emitter assumed that the arch-specific NLR was used
instead of the setjmp/longjmp based NLR code. If the latter NLR
provider was chosen, the emitter would allocate space on the stack
for the NLR buffer but would not fill it in.
This change turns off setjmp()-based NLR and GCREGS for the ESP32C3
target, in favour of more platform-tailored alternatives. As setjmp()
NLR is now disabled by default, the RV32 emitter can be safely enabled
by default as well for the target in question.

Install the mingw variant of Python since it behaves more like a 'real'
Windows CPython than the msys2 variant: os.name == 'nt', not 'posix'. Note
that os.sep is still '/' though so we don't actually need to skip the
import_file test. This way one single Python version can be used both for
running run-tests.py and getting the expected test output.

This adds a CPython diff that explains why calling `super().__init__()` is

When subclassing a native type, calling native members in `__init__` before
`super().__init__()` has been called could cause a crash. In this
situation, `self` in `mp_convert_member_lookup` is the
`native_base_init_wrapper_obj`. The check added in this commit ensures
that an `AttributeError` is raised before this happens, which is consistent
with other failed lookups.
Also fix a typo in a related comment.

Having IPv6 support is important, especially for IoT-Devices which might be
many, requiring individual IP-addresses. In particular direct access via
link-local addresses and having deterministic SLAAC-addresses can be quite
convenient. Also in IPv6-only networks or for connecting to IPv6-only
services, this is very useful.
For the Pico W, there is enough flash and RAM that enabling IPv6 by default
is the right choice.
Should IPv6 support in a network exist (i.e. there are Router
Advertisements), but not provide connectivity, connecting by domain name
should not be a problem as DNS will default to return the IPv4-address (if
that exists), unless reconfigured at runtime to prefer IPv6.
In any case a user can disable obtaining SLAAC-addresses with:
<nic>.ipconfig(autoconf6=False)

Updates rp2 port to always resume from idle within 1ms max.
When rp2 port went tickless the behaviour of machine.idle() changed as
there is no longer a tick interrupt to wake it up every millisecond. On a
quiet system it would now block indefinitely. No other port does this.
See parent commit for justification of why this change is useful.
Also adds a test case that fails without this change.

A lot of existing code (i.e. micropython-lib lps22h, lcd160cr sensor
drivers, lora sync_modem driver, usb-device-hid) calls machine.idle()
inside a tight loop that is polling some condition. This reduces the power
usage compared to constantly looping, but can be faster than calling a
sleep function. However on a tickless port there's not always an interrupt
before the condition they are polling for, so it's difficult to restructure
this code if machine.idle() doesn't have any upper limit on execution time.
This commit specifies an upper limit of 1ms before machine.idle() resumes
execution. This is already the case for all ports except rp2.

If core1 executes `mp_wfe_or_timeout()` then it needs to receive an
interrupt or a SEV to resume execution, but the soft timer interrupt only
fires on core 0. This fix adds a SEV to the soft timer interrupt handler.
This issue was masked by the issue fixed in the previous commit, as WFE
previously wasn't suspending properly.
Verified via the existing thread_sleep2 test.

Fixes a regression introduced in 3af006efb39ad0b7aa7c0401c93329b654bca617
where WFE never blocked in `mp_wfe_or_timeout()` function and would
busy-wait instead. This increases power consumption measurably.
Root cause is that `mp_wfe_or_timeout()` calls soft timer functions that
(after the regression) call `recursive_mutex_enter()` and
`recursive_mutex_exit()`. The exit calls
`lock_internal_spin_unlock_with_notify()` and the default pico-sdk
implementation of this macro issues a SEV which negates the WFE that
follows it, meaning the CPU never suspends.
See https://forums.raspberrypi.com/viewtopic.php?p=2233908 for more
details.
The fix in this comment adds a custom "nowait" variant mutex that doesn't
do WFE/SEV, and uses this one for PendSV. This will use more power when
there's contention for the PendSV mutex as the other core will spin, but
this shouldn't happen very often.
