refactor: Improve CAN and UART handling, add documentation and checks 

- Fixed UART speed inside handle and CAN speed inside handle for runtime configuration.
- Moved CAN filter setup inside the handle for more centralized control.
- Added documentation above functions for better readability.
- Included argument checks at function entry to ensure valid parameters.
- Added runtime checks to prevent memory corruption where values can change dynamically.
- Removed unnecessary `extern` declarations to improve code clarity.
- Fixed `vMCAL_MCAN_Tx()` to return success even if `if (sMcalTxFifoStatus_x.freeLvl)` fails.
- Removed unused functions to clean up the codebase.
- Fixed `xMCAL_VrefInit()` by calling vMCAL_SoftReset.
