Add fault handling and watchdog safety infrastructure: - hardFaultHandler: ARM Cortex-M4 HardFault handler in assembly — captures register state (R0-R12, LR, PC, PSR) for post-mortem analysis - safeBspMcuWatchdog: IWDG (Independent Watchdog) driver with configurable timeout, kick interface, and reset-reason detection - SafetyManager: Board-level safety lifecycle integration for G474RE Milestone: cmake configures with safety modules. Watchdog activates with PR 6 (RTOS). Depends on eclipse-openbsw#416 (PR 4: FDCAN transceiver). PR 5 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.

Add bxCAN and FDCAN device drivers with STM32 CAN tests. Add the bxCAN transceiver adapter and unit-test registration.
Add the FDCAN transceiver implementation and STM32 test coverage. Wire the FDCAN transceiver into the chip-family CMake selection.

Purpose of this PR
Description
Fourth PR in the STM32 platform series. Adds the FDCAN transceiver adapter, completing CAN support for both STM32 families.
Module added
fdCanTransceiverICanTransceiveradapter for STM32G4 FDCAN peripheralMirrors the bxCAN transceiver (PR 3) but supports FD frames with up to 64-byte payload and extended filter configuration.
Milestone
Both CAN transceiver variants (bxCAN + FDCAN) now available. Tests: FdCanTransceiverTest, FdCanTransceiverIntegrationTest.
Depends on #415 (PR 3: CAN drivers). PR 4 of 10.
