Darian Leung 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.

esp_hw_support

This component contains hardware-related operations for supporting the system. These operations are one level above that of hal in that these(1) use system services such as memory allocation, logging, scheduling or (2) may be multi-step operations involving/affecting multiple parts of the SoC.

Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
