6c66018d5b refactor(freertos/smp): Move vTaskStartSchedulerOtherCores() to API additions to headers
- Move vTaskStartSchedulerOtherCores()
    - implementation to freertos_tasks_c_additions.h
    - declaration to freertos_idf_additions_priv.h as API is private
- Rename vTaskStartSchedulerOtherCores() -> prvStartSchedulerOtherCores() to
indicate that the function is private.

550ecbe37a feat(freertos): added POSIX/Linux simulator port to FreeRTOS SMP
* Added a POSIX/Linux simulator that is compatible with the Amazon
  FreeRTOS SMP API. Note that the simulator itself is still
  single core, like the IDF FreeRTOS POSIX/Linux simulator.

0cf1fd3a5a freertos: Add multi-core OS startup race condition workaround
FreeRTOS uses a single "xSchedulerRunning" variable to tack whether the
scheduler has started, and this variable is set to "pdTRUE" by core 0
via calling vTaskStartScheduler().

However, with SMP FreeRTOS, there is a race condition where core 0 has
already started the scheduler and another core has not called xPortStartScheduler()
yet and calls some FreeRTOS API. Thus the resultant FreeRTOS API can
cause errors as it thinks the scheduler has started.

This commit adds a temporary workaround (by having each core maintain their
own "xSchedulerRunning" variable.

7726f343e8 freertos-smp: Update prvYieldCore() to fix compile warning
prvYieldCore() leads to an array-out-of-bounds error when compiled with
-Os optimization and configNUM_CORES = 1. This commit avoids this
compile warning by compiling out the part of code which is unnecessary
when configNUM_CORES is 1.

283f569a03 freertos-smp: refactor thread local storage pointers deletion callbacks
This commit updates how the TLS pointers deletion callbacks are called
during task deletion in the FreeRTOS SMP kernel. The callbacks are now
routed through the portCLEAN_UP_TCB() macro. This commit also adds a
new kconfig option CONFIG_FREERTOS_TLSP_DELETION_CALLBACKS to control
the enablement of the TLSP deletion callbacks.

8c92d0b2af freertos: Disable portUSING_MPU_WRAPPERS in FreeRTOS SMP Xtensa port
This commit disables portUSING_MPU_WRAPPERS for the FreeRTOS SMP xtensa port.
This was previously enabled due to the need to keep a CPSA (coprocessor save
area pointer) in the TCB. The CPSA pointer is now calculated at run time.

2d1afaf35b freertos: Add FreeRTOS SMP upstream files
This commit copies over the sources files from
https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/smp based on the
commit 4832377117b4198db43009f2b548497d9cdbf8da

The FreeRTOS SMP sources are added to components/freertos/FreeRTOS-Kernel-SMP

Notes:
- This commit WILL NOT compile correctly. It simply copies over sources files
- copyright_ignore.txt entries added so that we can avoid using SPDX headers
- Portable files are not added yet
