perf(core): enable MICROPY_ROM_TEXT_COMPRESSION

Using micropython/micropython#5861 to reduce flash usage by 2.56kB on T3T1:

Since we use -ffreestanding in SConscript.firmware, I have re-mapped strcmp to __builtin_strcmp (b7c64ca) otherwise MICROPY_ROM_TEXT_COMPRESSION compile-time optimization doesn't work.
See micropython/micropython#17196 (comment) for more details.

BTW, applying similar approach for untranslated strings may help us save ~6kB:

$ python vendor/micropython/py/makecompresseddata.py <(jq -r .translations[] core/translations/en.json)

Will rebase to resolve a merge conflict.

Retargeted over main to include d852931 (updating MicroPython to include trezor/micropython#25).
