Update GD32F30x CMSIS HAL to v3.0.3

Update CMSIS HAL files to firmware version 3.0.3 with enhanced stability during clock frequency switching. Key changes include:

- Improved RCU_MODIFY macro for Vcore fluctuation prevention
- Added software delay function to stabilize transitions
- Converted direct register writes to read-modify-write pattern in clock functions
- Added firmware version query support
- Updated copyright year to 2026
- Removed deprecated GCC diagnostic pragmas
- Added HardFault_IRQn to interrupt enumeration
