change(freertos/smp): Update stream_buffer.c locking

Browse source 
Updated stream_buffer.c to use granular locking

- Added xTaskSpinlock and xISRSpinlock
- Replaced critical section macros with data group critical section macros
such as taskENTER/EXIT_CRITICAL/_FROM_ISR() with sbENTER/EXIT_CRITICAL_FROM_ISR().
- Added vStreambuffersEnterCritical/FromISR() and
  vStreambuffersExitCritical/FromISR() to map to the data group critical
section macros.
- Added prvLockStreamBufferForTasks() and prvUnlockStreamBufferForTasks() to suspend the stream
buffer when executing non-deterministic code.
