When you wish to use the valgrind memory analysis tool on micropython,
you can arrange to define MICROPY_DEBUG_VALGRIND to enable use of
special valgrind macros. For now, this only fixes `gc_get_ptr`
so that it never emits the diagnostic "Conditional jump or move depends
on uninitialised value(s)".

Convert bitbangio, bitmaptools, _bleio, board, busio, countio, digitalio, framebufferio, frequencyio, gamepadshift, getpass, keypad, math, microcontroller, and msgpack modules to use MP_REGISTER_MODULE.
Related to #5183.
Convert adafruit_bus_device, adafruit_pixelbuf, analogio, atexit, audiobusio, audiocore, audioio, audiomixer, and audiomp3 modules to use MP_REGISTER_MODULE.
Related to #5183.
Convert from using MICROPY_PORT_BUILTIN_MODULES_STRONG_LINKS to using MP_REGISTER_MODULE for displayio, terminalio, and fontio modules.

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 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.
