9b81e2b189 freertos: Schedule tasks unblocked by an ISR on a core with scheduler running if core affinity matches
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.

29ec3fbacf xtensa: Move default vectors back into xtensa_vectors.S
The default implementation of some xtensa vectors were previously moved to
"xtensa_vector_defaults.S" as weak functions so that they could be overriden.

This commit moves these default vectors back into "xtensa_vectors.S" in
preparation for further refactoring of the xtensa component.

353b25410a freertos: Refactor configASSERTs for scheduler suspension
This commit adds a common macro for the differing configASSERT() calls that
check if the scheduler is suspended outside a critical section. This macro
allows vanilla behavior to be restored for single core builds. Also added
comments explaining why xTaskGetSchedulerState() is called instead when
building for SMP.

e21ab0332b freertos(IDF): Refactor port heap functions
Vanilla FreeRTOS expects applications to use one of the heap implementations
provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc()
and vPortFree() are defined in the heap implementation.

However, ESP-IDF already provides its own heap implementation
(i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were
previously overriden by macro to call esp_heap functions directly.

This commit refactors the FreeRTOS port's heap as such:

- Added a heap_idf.c that implements all of the heap related functions required
  by FreeRTOS source
- All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the
  FreeRTOS heap is the internal memory subset of the ESP-IDF heap.
- Removed some old macros to reduce diff from upstream source code.

45badf864f freertos(IDF): Allow cross-core freeing of task memory when deleting tasks
Previously, IDF FreeRTOS would restrict the clean up of task memory (done by
vTaskDelete() or the Idle task) to only tasks pinned to the current core or
unpinned tasks. This was due to the need to clear the task's coprocessor
ownership on the other core (i.e., "_xt_coproc_owner_sa"). But this restriction
can be lifted by simply protecting access of "_xt_coproc_owner_sa" with a
spinlock.

This commit implements a "_xt_coproc_owner_sa_lock" to protect the access of
"_xt_coproc_owner_sa", thus vTaskDelete() and prvDeleteTCB() can now delete
tasks pinned to the other core so long as that task is not currently running.

Note: This fix was copied from the Xtensa port of Amazon SMP FreeRTOS

c318c89453 freertos(IDF): Remove dependency on portUSING_MPU_WRAPPERS
This commit removes the dependency on portUSING_MPU_WRAPPERS on the Xtensa port
of IDF FreeRTOS. This dependency was added due to a hack implemented in the
upstream port that required the usage of the "xMPUSettings" member of the TCB.
The "xMPUSettings" would be used as a pointer to the task's coprocessor save
area on the stack, even though FreeRTOS MPU support was not available.

The hack has now been removed, and the CPSA pointer is now calculated using
a combination of constant offsets values and the pxEndOfStack member of the
TCB.

Note: This impelemtation was copied from the Xtensa port of Amazon SMP FreeRTOS.

09690906e7 freertos: Refactor OS startup functions
This commit refactors the OS startup functions as follows:

- Moved the OS/app startup functions listed below to "app_startup.c". Their
    implementations are now common to all ports (RISC-V and Xtensa) of all
    FreeRTOS implementations (IDF and Amazon SMP).
    - esp_startup_start_app()
    - esp_startup_start_app_other_cores()
- Removed esp_startup_start_app_common() as app startup functions are now
    already common to all ports.
- Added extra logs to "main_task" to help with user debugging

Note: Increased startup delay on "unity_task". The "unity_run_menu()" is non
blocking, thus if the main task or other startup tasks have not been freed
by the time "unity_run_menu()" is run, those tasks will be freed the next time
"unity_task" blocks. This could cause some tests to have a memory leak, thus
the "unity_task" startup delay has increased.

8b98e4e3b8 freertos(IDF): Restore vanilla call behavior on xTaskIncrementTick() and vTaskSwitchContext()
Due to SMP, critical sections have been added to xTaskIncrementTick() and
vTaskSwitchContext() (to take the xKernelLock). However, this is technically
not necessary when building for single-core as FreeRTOS expect these funcitons
to be called with interrupts already disabled.

This commit makes the critical secitons in those functions depend on
"configNUM_CORES > 1", and ensures that interrupts are disabled when calling
those functions. This effectively restores the vanilla behavior for these
functions when building for single-core.

087e4318a6 freertos(IDF): Use common macros for SMP specific critical sections
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.

ae3383ddc5 freertos: Remove/restore queue locks for multi-core/single-core
This commit removes the updates the usage of queue locks in IDF FreeRTOS

Queue locks are present in Vanilla FreeRTOS to ensure that queue functions
behave deterministicly in critical sections (i.e., no walking linked lists
while interrupts are disabled). However, currently in IDF FreeRTOS...

- When configNUM_CORES > 1, IDF FreeRTOS drops the determinism requirement.
Thus, queue functions could be simplified if queue locks were not used at all
(and have a queue function do everything inside the same critical section).

- When configNUM_CORES == 1, the current queue implementation in IDF FreeRTOS
does not meet the determinism requirements, as critical sections are used
(instead of scheduler suspension) when locking/unlocking the queues.

There, this commit updates multiple queue functions so that

- When configNUM_CORES > 1
    - Queue locks are no longer used. All actions are done within the same
      critical section.
    - Affected queue functions now need 40% less CPU clock cycles when blocking
- When configNUM_CORES = 1
    - Queue locks are still used.
    - Vanilla behavior of suspending the scheduler is restored when locking
      the queue. Thus queue fucntions are now deterministic and have the same
      behavior as Vanilla FreeRTOS.
    - Affected queue functions now takes 36% more CPU clock cycles when
      blocking (due to the scheduler suspension/resumption).

4. CONFIG_FREERTOS_IDLE_TASK_STACKSIZE is now incorporated into the
   FreeRTOSConfig_smp.h to configure the IDLE0 stack size.

This commit refactors the way stream buffers initialize their spinlock.

- Stream buffer creation functions now manually initialize the spinlock after
