graham sanderson 5d161b79bb Fix up build_family style builds: ...

- added back pre-existing board directories which now just select PICO_BOARD
 - added boards/pico_sdk which just uses the pre-existing PICO_BOARD setting
 - fixed rp2040/family.cmake to include the magic string "CFG_TUSB_MCU=OPT_MCU_RP2040" expected by build_family.py
