pewpew m4: enable CDC back

[deshipu]

CDC got disabled on this board by mistake

[deshipu]

This should fix #7498 7498

[dhalbert]

@deshipu Now some languages don't quite fit. These are the included modules from the last RTD build:

_stage, analogio, array, audiocore, audioio, audiomixer, board, builtins, busio, collections,
digitalio, displayio, fontio, keypad, math, microcontroller, nvm, os, random, storage, struct,
supervisor, synthio, sys, terminalio, time, watchdog, zlib

Frozen Modules: pew, stage, ugame

There are some specialized disablers you could use:

CIRCUITPY_BUSIO_SPI = 0         no busio.SPI
CIRCUITPY_BUSIO_UART = 0     no busio.UART

Also this can squeeze some space, at the expense of some performance of the VM

CIRCUITPY_COMPUTED_GOTO_SAVE_SPACE = 1

[FoamyGuy]

We could try disabling zlib with CIRCUITPY_ZLIB = 0 instead of current 1.

I didn't check all the languages, but did try a few and got successful builds from this branch with the change to disable zlib.

[deshipu]

@FoamyGuy I need zlib to decode png images.
@dhalbert I think we can disable analogio, I will update the PR.

[deshipu]

Also disabled watchdog

[dhalbert]

Thanks for the quick work on this. It will be in rc.0.
