Guard LR1121/LR2021 radio configs with #ifdef (#10998)

Browse Source 
Add conditional compilation guards for LR1121 and LR2021 radio chip configurations in rfswitch.h to prevent compilation errors when these radios are not in use. Move USE_LR2021 definition to the radio section in variant.h for consistency with other radio chip definitions.
