feat(granular_locks): Add granular locking functions

Browse source 
- Updated prvCheckForRunStateChange() for granular locks
- Updated vTaskSuspendAll() and xTaskResumeAll()
    - Now holds the xTaskSpinlock during kernel suspension
    - Increments/decrements xPreemptionDisable. Only yields when 0, thus allowing
    for nested suspensions across different data groups
