5f815b8a2d unix: Enable exit code handling for sys.exit().
Enable `MICROPY_PYEXEC_ENABLE_EXIT_CODE_HANDLING` to propagate `sys.exit()`
exit codes properly. Update `convert_pyexec_result()` to handle return
values where pyexec returns the exit code with `PYEXEC_FORCED_EXIT` flag
set for `SystemExit`. Extract the exit code from the lower 8 bits when the
flag is set, otherwise return as-is (0 for success, 1 for exception).

fd1ddc3f12 shared/runtime/pyexec: Call mp_hal_stdio_mode_orig/raw as appropriate.
This ensures that ctrl-C works on the unix port when executing code at the
REPL.

e06ac9ce08 unix/main: Replace execute_from_lexer with pyexec in do_file and do_str.
Consolidates file and string execution to use the standard pyexec interface
for consistency with other ports.

Simplify execute_from_lexer for remaining usage: Remove unused LEX_SRC_VSTR
and LEX_SRC_FILENAME cases, keeping only LEX_SRC_STR for REPL and
LEX_SRC_STDIN for stdin execution.

5b3c928f53 unix/main: Use standard pyexec REPL for unix and windows ports.
This improves REPL usage consistency across ports, by utilizing the pyexec
code for the unix REPL.

RP2350 builds were using the incomplete `rp2_af.csv` alt function table
(originally made for RP2040) which broke pins > 31 in RP2350B (48-pin
QFN-80) builds:

    >>> machine.Pin(31)
    Pin(GPIO31, mode=IN, pull=PULL_DOWN)

    >>> machine.Pin(32)
    Pin(GPIO32, mode=ALT, pull=PULL_DOWN, alt=31)

To fix this, separate alt-functions tables for RP2350 and RP2350B are added
in this commit.

UART_AUX (alt function 11) was also missing, along with XIP_CS1 and
CORESIGHT_TRACE, and they are  now added as well.

e74367684e zephyr: Introduce Zephyr native filesystem VFS interface.
This allows using Zephyr's supported VFS and interface it to MicroPython's
VFS.  That makes the MicroPython-side filesystem drivers unecessary, eg you
can disable LFS2 in MicroPython but still do LFS2 because it's using
Zephyr's.

An advantage of this is that the filesystem can be shared between Zephyr C
code and MicroPython.

9f87b79142 stm32/eth: Implement zero-copy of lwIP pbufs for TX path.
This option (currently only enabled for N6) allows the TX path to hold on
to a pbuf reference while the DMA accesses the pbuf's memory directly,
instead of copying the entire pbuf data into the internal buffers.

This is necessary to achieve gigabit speeds on the N6, although actually
achieving that speed requires higher up parts of the stack to be efficient
as well.

4e79698a99 rp2/pendsv: Fix PendSV_Handler dispatch check when threading enabled.
If MICROPY_PY_THREAD is set, PendSV_Handler acquires a mutex and calls the
dispatch functions. If pendsv_schedule_dispatch is called by a higher
priority interrupt while the mutex is acquired by PendSV_Handler it's
possible for the dispatch to not be triggered.

Add a check for dispatch calls at the end of PendSV_Handler once the mutex
has been released.

Fixes issue #18365.

713f9dcd22 esp32: Fix USB Zero Length Packet issue with patched tinyusb.
Temporarily switch from the espressif TinyUSB component to
a MicroPython fork where this fix has been cherry-picked:

4f193132d2 esp32: Remove dependency on esp_tinyusb.
Instead, depend directly on espressif/tinyusb component
(which is otherwise transitively included via esp_tinyusb).

Turns out esp_tinyusb builds a bunch of source files with
symbols that conflict with our tinyusb symbols (i.e.
descriptors_control.c).

This only works because nothing in MicroPython causes the linker to include
the esp_tinyusb.a library, however in order to override the dcd_int_handler
(in following commit) this caused the linker to pull this library in and
break the build.

There's also a problematic header skew - TinyUSB component was building
with the tusb_config.h file from esp_tinyusb component, but we have our own
tusb_config.h file in shared/tinyusb. The changes in parent commit allow
us to build the TinyUSB component with our tusb_config.h header.

User-facing impacts are:

- Can no longer override USB VID & PID via sdkconfig, have to set
  MICROPY_HW_USB_VID/PID instead (changes applied in this commit).

- esp32 boards will have the same USB serial number as other ports
  (i.e. based on the hardware MAC address, not hard-coded).

Side effects include:

- CFG_TUD_DWC2_SLAVE_ENABLE is now set, DMA mode is disabled.

a435e4ecfd esp32: Take global dependencies out of mpconfigport.h.
This is necessary so the ESP-IDF TinyUSB component can include
py/mpconfig.h, but is also a good design goal (less creep of symbols
into unrelated parts of the code).

4766f5680e esp32: Fix USB deinit/reinit path via soft reset.
Fixes problems with USB-CDC state after soft reset if USBDevice has been
active with the default USB-CDC driver also enabled.

This also brings ESP32 behaviour in line with RP2 and other ports, where
boot.py is executed before the runtime USB device is initialised. This
allows setting up a custom USB device in boot.py.

There is still a bug here, because calling tud_disconnect() doesn't cause
any UNPLUG or BUS_RESET events to arrive from TinyUSB - which means the USB
device state stays out of sync until we call mp_usbd_init() again...

The current `esp32.RMT` class uses a legacy API from ESP-IDF 4.x.  The
ESP-IDF 5.x offers a new API, which is overall better, and easier to
implement the RX side in the future.  This commit updates the module and
the documentation, preserving the current MicroPython RMT API as much as
possible.

The bitstream RMT implementation was updated as well, since ESP-IDF does
not allow firmware to reference legacy and new APIs at the same time (it
resets right after boot with an error message, even if neither module is
imported).

The documentation is updated accordingly.

TinyUSB's `dwc2_phy_init()` only sets the PWRDWN bit in the GCCFG register
but doesn't configure VBUS sensing, which is required for the DWC2 USB
controller to detect host connection on STM32F4 and STM32F7 series.

Without VBUS sensing configured, USB devices fail to enumerate on these
platforms when using the TinyUSB stack, while the legacy STM32 USB stack
works because it includes this configuration.

This commit adds VBUS sensing configuration in `pyb_usbd_init()` for
TinyUSB mode on STM32F4/F7:
- When VBUS detect pin is configured (typically PA9): Enable "B device"
  VBUS sensing (USB_OTG_GCCFG_VBUSBSEN)
- When no VBUS pin: Force VBUS valid (USB_OTG_GCCFG_NOVBUSSENS)

Tested on:
- NUCLEO-F429ZI: USB now enumerates successfully (CDC + MSC)
- NUCLEO-H563ZI: No regression (STM32H5 uses different register layout)

9bb266e311 stm32/usb: Add support for using TinyUSB stack.
This commit adapts the stm32 port to allow switching from STM USB stack to
TinyUSB stack.

Using TinyUSB improves consistancy with other MicroPython ports and brings
in the ability to use the runtime USB definition support recently added to
other TinyUSB based ports.

By default the existing STM USB stack is used.  TinyUSB can be enabled in a
board configuration with:

    #define MICROPY_HW_TINYUSB_STACK (1)

Or, it can be enabled from the command line with:

    make -C ports/stm32 CFLAGS_EXTRA='-DMICROPY_HW_TINYUSB_STACK=1'

Implemented the keyword-only parameter `invert` for the `UART.init` method
in accordance with the docs:
- added constants `UART.INV_TX` and `UART.INV_RX`
- added the new `invert` keyword parameter to the `uart_init` function
- adapted the `uart_init` call
- added invert setting to `uart_print` output

The feature applies only to STM32H7.

72e67f0f02 samd/machine_bitstream: Tune ticks for SAMD51 and set pin to output.
Changes in this commit:
- Change ticks overhead value for SAMD51.  The value was too large and thus
  timing was quite bad.  At 120Mhz it's now within +/- 30ns.
- Set the pin to output mode.  That way, all Pin identifiers are accepted
  as argument, not only Pin objects.

Tested with ItsyBitsy M4 and M0 boards.

849c67bcdc tests/run-tests.py: Pass auto-detected architecture flags to mpy-cross.
This commit lets "run-tests.py" use the encoded architecture flags
provided by the interpreter when invoking "mpy-cross".

If architecture flags are detected, they're mapped into the necessary
strings needed by "mpy-cross"'s "-march-flags" argument, so that tests
will always use all available extensions reported by the target.

Currently this is limited to the RV32 platform, as it is the only one
that is making use of this facility as of now.  This also lets the QEMU
port remove forced arguments to "mpy-cross" when running the test suite.
