This commit makes it so that MICROPY_PY_MACHINE_PWM is enabled if at least
one of MICROPY_PY_MACHINE_HW_PWM and/or MICROPY_PY_MACHINE_SOFT_PWM are
enabled. This simplifies the configuration for boards, and fixes DVK_BL652
which enabled PWM without selecting software or hardware implementations.
With this change, DVK_BL652 and EVK_NINA_B1 now enable (hardware) PWM.

This factors the basic top-level I2S class code from the ports into
extmod/machine_i2s.c:
- I2S class definition and method table.
- The init and deinit method wrappers.
- The make_new code.
Further factoring will follow.

With public declarations moved to extmod/modmachine.h. It's now mandatory
for a port to define MICROPY_PY_MACHINE_PWM_INCLUDEFILE if it enables
MICROPY_PY_MACHINE_PWM. This follows how extmod/machine_wdt.c works.
All ports have been updated to work with this modified scheme.

There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations. This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c. This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.
With this refactor the ports remain functionally the same except for:
- The esp8266 WDT constructor now takes keyword arguments, and accepts the
"timeout" argument but raises an exception if it's not the default value
(this port doesn't support changing the timeout).
- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
as signed and if it's negative truncate it to the minimum timeout (rather
than it being unsigned and a negative value truncating to the maximum
timeout).

The unwritten API contract expected of a VFS.getcwd() by mp_vfs_getcwd()
is that its return value should be either "" or "/" when the CWD is at
the root of the VFS and otherwise start with a slash and not end with a
slash. This was not correctly implemented in VfsPosix for instances with
a non-empty root - the required leading slash, if any, was cut off
because the root length includes a trailing slash. This would result in
missing slashes in the middle of the return value of os.getcwd() or in
uninitialized garbage from beyond a string's null terminator when the
CWD was at the VFS root.

The unwritten API contract expected of a VFS by mp_vfs_lookup_path() is
that paths passed in are relative to the root of the VFS if they start
with '/' and relative to the current directory of the VFS otherwise.
This was not correctly implemented in VfsPosix for instances with a
non-empty root - all paths were interpreted relative to the root. Fix
that. Since VfsPosix tracks its CWD using the "external" CWD of the Unix
process, the correct handling for relative paths is to pass them through
unmodified.
Also, when concatenating absolute paths, fix an off-by-one resulting in
a harmless double slash (the root path already has a trailing slash).

These tests test an unrealistic situation and only pass by accident due
to a bug. The upcoming fix for the bug would make them fail.
The unrealistic situation is that VfsPosix methods are called with
relative paths while the current working directory is somewhere outside
of the root of the VFS. In the intended use of VFS objects via
os.mount() (as opposed to calling methods directly as the tests do),
this never happens, as mp_vfs_lookup_path() directs incoming calls to
the VFS that contains the CWD.
Make the testing situation realistic by changing the working directory
to the root of the VFS before calling methods on it, as the subsequent
relative path accesses expect.
Thanks to the preceding commit, the tests still pass, but still for the
wrong reason. The following commit "Fix relative paths on non-root VFS"
will make them pass for the correct reason.

A VfsPosix created with a relative root path would get confused when
chdir() was called on it and become unable to properly resolve absolute
paths, because changing directories effectively shifted its root. The
simplest fix for that would be to say "don't do that", but since the
unit tests themselves do it, fix it by making a relative path absolute
before storing it.

The main thread gets this because the thread state is in bss, but
subsequent threads need this field to be initialised.
Also added a note to mpstate.h to help avoid missing this in the future.

This commit implements Ethernet support for STM32H5. Changes are:
- Add Cortex-M33 MPU code. Ethernet driver requires MPU to define cache
strategy for DMA buffers (descriptors and frames).
- Add support for STM32H5 Ethernet controller. The controller is mostly
compatible with the STM32H7. However the descriptor layout is different.
- Adapt clocking and reset for STM32H5.
Tested on NUCLEO-H563ZI and STM32H573I-DK, using ping and iperf3. TCP
rates of 80-90 Mbits/sec were achievable.

This wasn't correctly accounting for the bits-per-pixel and was returning a

This ensures that the buffer is large enough for the specified width,
height, bits-per-pixel, and stride.
Also makes the legacy FrameBuffer1 constructor re-use the FrameBuffer

This allows mp_get_buffer_raise() to be changed to a simple inline function
that in the majority of cases costs the same (in code size) to call as the
original mp_get_buffer_raise(), because the flags argument is a constant.

This behaviour matches CPython. It's useful to be able to store bound

Sometimes these are different file descriptors, not to mention the Unix
port, so use stderr to distinguish these error messages.
CPython prints to stdout, but it does it via a call to the logging module.
We don't want to introduce a dependency on logging, so printing to stderr
is a good alternative. One can override default_exception_handler() if
needed.
If a non-string buffer was passed to execfile, then it would be passed
as a non-null-terminated char* to mp_lexer_new_from_file.
This changes mp_lexer_new_from_file to take a qstr instead (as in almost
all cases a qstr will be created from this input anyway to set the
`__file__` attribute on the module).
This now makes execfile require a string (not generic buffer) argument,
which is probably a good fix to make anyway.

That can be caused e.g. by an exception. This feature is implemented in
some way already for the stm32, renesas-ra, mimxrt and samd ports. This
