feat(mrm_handler): operate mrm only when autonomous operation mode (autowarefoundation#7784)

* feat: add isOperationModeAutonomous() function to MRM handler core

The code changes add a new function `isOperationModeAutonomous()` to the MRM handler core. This function is used to check if the operation mode is set to autonomous.
