FromISR APIs would put an unblocked task on the pending ready list if
the scheduler is suspended on the current core, irrespective of the
task's core affinity and the state of the scheduler on the other core.
This commit updates this behavior by allowing tasks to get scheduled on
a core which has the scheduler running as long as the task's core
affinity allows it.
This commit updates the ESP-IDF FreeRTOS and FreeRTOS Additions to account for
the fact that there are now two implementations of SMP FreeRTOS (i.e., IDF SMP
vs Amazon SMP).
This commit renames "freertos-smp" docuemnt to "freertos_idf". This fits better
with the current dual FreeRTOS implementation (i.e., IDF FreeRTOS and Amazon
SMP FreeRTOS), both of which are SMP capable.
