DEBUG_MUTE (set for all of stm32) already compiles every LOG_* call
out entirely at the preprocessor stage, but nanopb's own error-message
strings are a separate mechanism it doesn't touch - PB_RETURN_ERROR
still embeds descriptive text in .rodata regardless of whether
anything ever logs it.
Rather than hardcoding -DPB_NO_ERRMSG=1 next to every place DEBUG_MUTE
is set, derive it in bin/platformio-custom.py via the SCons build
environment, mirroring the existing meshtastic-device-ui/APP_VERSION
CPPDEFINES pattern already in that file. This reaches both the main
project env and the Nanopb library builder specifically, since nanopb
is a separate LibraryBuilder whose own CPPDEFINES aren't otherwise
touched by a plain env.Append() on the app env. The CPPDEFINES
membership check normalizes both bare (-DDEBUG_MUTE) and value-bearing
(-DDEBUG_MUTE=1) forms, since SCons represents the latter as a tuple.
DEBUG_MUTE currently only appears in variants/stm32/stm32.ini and
variants/stm32/milesight_gs301/platformio.ini, so today this only
affects stm32wl builds - but it will apply automatically to any future
platform that sets DEBUG_MUTE too, without that platform's .ini
needing to know about the pairing. Saves 1,248 bytes flash on wio-e5,
no RAM change, no feature loss beyond terser protobuf decode/encode
error text.
