Add the FdCanTransceiver module — OpenBSW ICanTransceiver adapter for STM32G4 FDCAN peripheral. Mirrors the bxCAN transceiver from PR 3 but supports FD frames (up to 64-byte payload) and extended filter banks. - FdCanTransceiver: ICanTransceiver implementation for FDCAN - Unit tests with mock FdCanDevice headers for host verification - Updated bsp/CMakeLists.txt for CAN_TYPE-based transceiver selection Milestone: `cmake --preset tests-stm32-debug` configures with both transceivers. Depends on eclipse-openbsw#415 (PR 3: bxCAN/FDCAN drivers). PR 4 of 10.

Import the STM32F4 and STM32G4 CMSIS device headers from STMicroelectronics' dedicated RIM-tracked repositories. Keep only the F413 and G474 headers needed by the STM32 MCU foundation and record the unused upstream headers as RIM ignores.
Add the STM32 platform entry point, chip CMake files, bspMcu startup code, a software reset wrapper, and the STM32 unit-test presets. The platform reuses the shared CMSIS core from libs/3rdparty/cmsis instead of carrying a local copy.
Add STM32 BSP modules for clock, UART, GPIO, timer, ADC, and EEPROM, plus interrupt handling primitives and the ETL platform glue.
