Convert adafruit_bus_device, adafruit_pixelbuf, analogio, atexit, audiobusio, audiocore, audioio, audiomixer, and audiomp3 modules to use MP_REGISTER_MODULE.

Convert from using MICROPY_PORT_BUILTIN_MODULES_STRONG_LINKS to using MP_REGISTER_MODULE for displayio, terminalio, and fontio modules.

This is a generic API for synchronously bit-banging data on a pin.
Initially this adds a single supported encoding, which supports controlling
WS2812 LEDs.

This was missed in 692d36d779. It's not
strictly necessary as the GC will clean it anyway, but it's good to
pre-emptively gc_free() all the blocks used in lexing/parsing.

This also tweaks the repr for unicode strings to only escape a few
utf-8 code points. This makes emoji show in os.listdir() for
example.
Also, enable exfat support on full builds.
Fixes#5146
This implements (most of) the PEP-498 spec for f-strings and is based on
https://github.com/micropython/micropython/pull/4998 by @klardotsh.
It is implemented in the lexer as a syntax translation to `str.format`:
f"{a}" --> "{}".format(a)
It also supports:
f"{a=}" --> "a={}".format(a)
This is done by extracting the arguments into a temporary vstr buffer,
then after the string has been tokenized, the lexer input queue is saved
and the contents of the temporary vstr buffer are injected into the lexer
instead.
There are four main limitations:
- raw f-strings (`fr` or `rf` prefixes) are not supported and will raise
`SyntaxError: raw f-strings are not supported`.
- literal concatenation of f-strings with adjacent strings will fail
"{}" f"{a}" --> "{}{}".format(a) (str.format will incorrectly use
the braces from the non-f-string)
f"{a}" f"{a}" --> "{}".format(a) "{}".format(a) (cannot concatenate)
- PEP-498 requires the full parser to understand the interpolated
argument, however because this entirely runs in the lexer it cannot
resolve nested braces in expressions like
f"{'}'}"
- The !r, !s, and !a conversions are not supported.
Includes tests and cpydiffs.

This leaves much more space on SAMD21 builds that aren't "full builds".
These are new APIs that we don't need to add to old boards.
Also, tweak two Arduino boards to save space on them.
* The new nonstandard '%S' format takes a pointer to compressed_string_t
and prints it
* The new mp_cprintf and mp_vcprintf take a format string that is a
compressed_string_t
By storing "count of words by length", the long `wends` table can be
replaced with a short `wlencount` table. This saves flash storage space.
Extend the range of string lengths that can be in the dictionary.
Originally it was to 2 to 9; at one point it was changed to 3 to 9.
Putting the lower bound back at 2 has a positive impact on the French
translation (a bunch of them, such as "ch", "\r\n", "%q", are used).
Increasing the maximum length gets 'mpossible', ' doit être ',
and 'CircuitPyth' at the long end. This adds a bit of processing time
to makeqstrdata. The specific 2/11 values are again empirical based on
the French translation on the adafruit_proxlight_trinkey_m0.
Commit 4173950658 removed automatic building
of mpy-cross, which rebuilt it whenever any of its dependent source files
changed.
But needing to build mpy-cross, and not knowing how, is a frequent issue.
This commit aims to help by automatically building mpy-cross only if it
doesn't exist. For Makefiles it uses an order-only prerequisite, while
for CMake it uses a custom command.
If MICROPY_MPYCROSS (which is what makemanifest.py uses to locate the
mpy-cross executable) is defined in the environment then automatic build
will not be attempted, allowing a way to prevent this auto-build if needed.
Thanks to Trammell Hudson aka @osresearch for the original idea; see #5760.

Optionally enabled via MICROPY_PY_UJSON_SEPARATORS. Enabled by default.
For dump, make sure mp_get_stream_raise is called after
mod_ujson_separators since CPython does it in this order (if both
separators and stream are invalid, separators will raise an exception
first).
Add separators argument in the docs as well.

do_execute_raw_code() from
MICROPY_PERSISTENT_CODE_LOAD
to
MICROPY_HAS_FILE_READER && MICROPY_PERSISTENT_CODE_LOAD
The condition that enables compiling the function itself needs to be

Previously a subclass of a type that didn't implement unary_op, or didn't
handle MP_UNARY_OP_BOOL, would raise TypeError on bool conversion.
Fixes#5677.
This adds #if MICROPY_PY_USELECT_SELECT around the uselect.select()
function. According to the docs, this function is only for CPython
compatibility and should not normally be used. So we can disable it
and save a few bytes of flash space where possible.

The MP_OBJ_STOP_ITERATION optimisation is a shortcut for creating a
StopIteration() exception object, and means that heap memory does not need
to be allocated for the exception (in cases where it can be used). This
commit allows this optimised object to take an optional argument (before,
it could only have no argument).
The commit also adds some new tests to cover corner cases with
StopIteration and generators that previously did not work.

I was puzzled by why the dictionary words were sorted by length.
It was because TextSplitter sorted its parameter, instead of a copy.
This doesn't affect encoding size, but does affect the encoding NUMBER
of the found words. We'll deliberately restore sorting by length next,
for other reasons, but not by spooky action.
Try to accurately measure the costs of including a word in the dictionary
vs the gains from using it in messages.
This saves about 160 bytes on trinket_m0 ja, the fullest translation
for that board. Other translations on the same board all have savings,
ranging from 24 to 228 bytes.

By comparing the address of the initial 'name' field instead of the
addresses of the objects themselves, a small amount of type safety is
added back, vs just casting to void.
In the event that some other kind of object is passed in as 't',
which happens to have a 'name' field of the right type, the construct
would be (undesirably) accepted but it would almost certainly evaluate
to false at runtime.
This adds the --tags argument to the git describe command that is used
to define the MICROPY_GIT_TAG macro. This makes it match non-annotated
tags. This is useful for MicroPython derivatives that don't use
annotated tags.
