Add STM32U3C5xx to the device selection list in stm32u3xx.h and map it to
stm32u3c5xx.h.

This enables the correct CMSIS device header include when building for
STM32U3C5xx targets and avoids the compile error:

Please select first the target STM32U3xx device used in your application

Looks ok, but please squash both commits, also, you'll need to update stm32cube/common_ll/README.rst (even if no change were done).
