freertos(IDF): Use common macros for SMP specific critical sections

Browse Source 
In IDF FreeRTOS, when building for SMP, there are numerous functions
which require different critical sections when compared to single-core. This
commit encapsulates those difference into a common set of macros whose
behavior depends on "configNUM_CORES > 1". As such...

- Vanilla behavior has been restored for some functions when building for
  single core (i.e., used to call taskENTER_CRITICAL, now disables interrupts
  mactching vanilla behavior).
- Reduces number of "#ifdef (configNUM_CORES > 1)" in functions
- Any SMP only critical sections are now wrapped by
  "#ifdef (configNUM_CORES > 1)" and properly documented via comments.
