rp2/boards/SOLDERED_NULA_MAX_RP2350: Add Soldered NULA Max board def.

The adds a board definition for the Soldered NULA Max RP2350 which has the
following features:
- RP2350 chip
- RP Radio Module 2
- MicroSD card reader
- 16MB of flash

The board contains initialization code for all said modules and settings.
