5d40016ddb freertos: fix thread safety for checking scheduler state
This issue was earlier fixed in commit 79e74e5d5f
but during migration to newer FreeRTOS release, it got introduced again.

This commit fixes thread safety issues with configASSERT() calls
regarding the value of uxSchedulerSuspended. A false negative
occurs if a context switch to the opposite core occurs in between
the getting the core ID and the assesment.

9b3796d2f1 freertos: Add portTRY_ENTRY_CRITICAL() and deprecate legacy spinlock fucntions
Add TRY_ENTRY_CRITICAL() API to all for timeouts when entering critical sections.
The following port API were added:
- portTRY_ENTER_CRITICAL()
- portTRY_ENTER_CRITICAL_ISR()
- portTRY_ENTER_CRITICAL_SAFE()

Deprecated legacy spinlock API in favor of spinlock.h. The following API were deprecated:
- vPortCPUInitializeMutex()
- vPortCPUAcquireMutex()
- vPortCPUAcquireMutexTimeout()
- vPortCPUReleaseMutex()

Other Changes:
- Added portMUX_INITIALIZE() to replace vPortCPUInitializeMutex()
- The assembly of the critical section functions ends up being about 50 instructions longer,
  thus the spinlock test pass threshold had to be increased to account for the extra runtime.

8376276b14 FreeRTOS: Fix xStreamBufferReset function always crashing
This function resets the spinlock given as a parameter after taking it
(when entering the critical section). This then results in a panic once
it tries to exit the same critical section.

8babb3bca6 freertos: Fix SMP round robin scheduling
The previous SMP freertos round robin would skip over tasks when
time slicing. This commit implements a Best Effort Round Robin
where selected tasks are put to the back of the list, thus
makes the time slicing more fair.

- Documentation has been updated accordingly.
- Tidy up vTaskSwitchContext() to match v10.4.3 more
- Increased esp_ipc task stack size to avoid overflow
