MIZAR32/mizar32_conf.f: Maintain same config for all Mizar32 devices

A quick check on the compilation for Mizar32-C (with bootloader set
as emblod) threw linker errors. Apparently, options like BUILD_TERM
were not defined for at32uc3a0128.

This commit enables them. PicoLisp can now be compiled for Mizar32-C
with bootloader=emblod.
PicoLisp's tmr subsystem: Include tmr_decode() in build

This function had been overlooked for the default build
CHANGELOG: "Updated PicoLisp doc in Mizar32 book"
