feat(granular_locks): Add granular locking functions
- 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
