Add a general normalize_newlines() function that handles newline variations
(\\r\\r\\n, \\r\\n) to \\n while preserving literal \\r characters that are
part of test content.
This provides a robust solution for cross-platform test compatibility,
particularly addressing PTY double-newline issues that can occur with some
terminal implementations.
The function is applied to all test output before comparison, eliminating
platform-specific newline issues.
Includes a unit test to verify the normalization behavior.

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(originally made for RP2040) which broke pins 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.

The currently documentation for ilistdir tuples says that the size element
is included based on the platform. However, this is not the case as it is
included based on the filesystem type. This commit makes the according
adjustment.

Currently, dict views (eg `dict.keys()`, `dict.values()`) do not implement
the `bool` or `len` unary operations. That may seem like a reasonable
omission for MicroPython to keep code size down, but it actually leads to
silently incorrect bool operations, because by default things are true.
Eg we currently have:
>>> bool(dict().keys())
True
which is wrong, it should be `False` because the dict is empty.
This commit implements `bool` and `len` unary operations on dict views by
simply delegating to the existing dict unary op function.
Fixes issue #12385.

The documentation used integers to specify Teensy board pins, which match
the board's silkscreen. But in Python code Dxx have to be used, since
integers are not accepted as a Pin identifier.
This commit changes the Pinout tables accordingly, consistent with the

Use new Zephyr FS, and be a demonstration of that configuration.

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.

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.

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.

Temporarily switch from the espressif TinyUSB component to

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.

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...

Not a functional change, but makes it easier to see that mp_usbd_init() is
available regardless of whether MICROPY_HW_ENABLE_USB_RUNTIME_DEVICE is
set.
Also adds a no-op inline mp_usbd_deinit() implementation, which means both
a port's calls to mp_usbd_init()/deinit() can both be guarded on the same
MICROPY_HW_ENABLE_USBDEV.

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.
