rp2/CMakeLists.txt: Set the appropriate mpy-cross flags on all targets.

This commit lets the RP2 port build system use the appropriate flags to
pass to "mpy-cross" when building frozen MPY files as part of the build
process.

Now all possible variants (RP2040, RP2350/Arm, and RP2350/RV32) have
their right flags assigned, falling back the flags set of the RP2040 if
a new variant is introduced.  Before these changes all variants would
use the RP2040 set of flags which may be a bit of an issue when building
code for the RP2350 in RV32 mode.
