Pull request overview
Adds TinyUSB support scaffolding for the new STM32C5 family (HAL2-based drivers) by wiring the MCU option into the STM32 FSDEV backend, adding a BSP/board definition, and updating dependency fetching + CI/docs accordingly.
Changes:
- Introduce
OPT_MCU_STM32C5and enable STM32 FSDEV (DRD, 2KB PMA) configuration paths for STM32C5. - Add STM32C5 BSP support (make/cmake build files, family implementation, Nucleo-C542 board files, HAL/FreeRTOS config headers).
- Update dependency lists, CI build matrix, board/docs lists, and example allowlists to include STM32C5.

stm32c5 uses HAL2 new driver which is a bit different.
