16ccb31d33 change(freertos/idf): Make v10.5.1 the default kernel
This commit makes v10.5.1 the default FreeRTOS kernel in ESP-IDF by removing
the CONFIG_FREERTOS_USE_KERNEL_10_5_1 option and v10.4.3 specific code
blocks.

db64e51e53 feat(freertos): Add SMP kernel changes to FreeRTOS v10.5.1
This commit adds the key kernel changes to the v10.5.1 kernel to support
dual-core SMP. These changes are temporarily documented in the `idf_changes.md`
document. This commit...

- Added changes to kernel data structures to support multiple cores
- Changes to scheduling algorithm support SMP scheduling.
- Changes to each FreeRTOS function to support multiple cores and SMP
scheduling algorithm.

035423eb37 refactor(freertos/idf): Move task creation "PinnedToCore" API to addition headers
This commit moves/merges the IDF FreeRTOS "PinnedToCore" task creation
functions from tasks.c/task.h to idf_additions.h/freertos_task_c_additions.h.

Also updated FreeRTOS Mock component to provide mocks for "idf_additions.h"
headers for our mock tests.

5de6a9aff6 refactor(freertos/idf): Move compatibility functions
This function moves ulTaskNotifyTake()/xTaskNotifyWait() from IDF FreeRTOS
`tasks.c` to `freertos_compatibility.c`. These functions were kept for
pre-compiled library compatibilty. Move them reduces the kernel source code
difference when compared to upstream FreeRTOS.

0db40f9e6c refactor(freertos/idf): Move IDF task utility functions to API addition headers
This commit combines various task utility API additions in IDF FreeRTOS and with
their Amazon SMP FreeRTOS addition counterparts. The folloiwng functions have
been moved to freertos_tasks_c_additions.h and idf_additions.h as these API
are considered public:

- xTaskGetCurrentTaskHandleForCPU()
- xTaskGetIdleTaskHandleForCPU()
- xTaskGetAffinity()
- pxTaskGetStackStart()

Also fixed in missing #if macros when vTaskCoreAffinityGet() is called in
Amazon SMP FreerTOS tests.

8825c8dda9 refactor(freertos/idf): Move critical section API to IDF addition headers
- The following IDF API additions are moved to freertos_tasks_c_additions.h
(implementation) and freertos_idf_additions_priv.h (declaration) as APIs are
private. This reduces the source code difference from upstream.
    - prvENTER_CRITICAL_OR_SUSPEND_ALL()
    - prvEXIT_CRITICAL_OR_RESUME_ALL()
    - prvENTER_CRITICAL_OR_MASK_ISR()
    - prvEXIT_CRITICAL_OR_UNMASK_ISR()
    - vTaskTakeKernelLock()
    - vTaskReleaseKernelLock()
- Rename vTask[Take/Release]KernelLock() to prv[Take/Release]KernelLock() to
indicate that the this API is private.

- Reorganized functions into groups
- linker_common.lf updated to adhere to new function organization

66499f17a5 freertos: Refactor component structure
This commit refactors the "freertos" component's structure as follows:

- "FreeRTOSConfig.h" related files moved to "./config" directory
- Refactored CMakeLists.txt file in preparation for v10.5.1 upgrade
    - Grouped list appends based on component organization
    - Removed some unecessarily public "include_dirs"
- Removed FreeRTOS-openocd.c
    - uxTopUsedPriority has been added back to tasks.c since v10.4.2
    - Thus the workaround in FreeRTOS-openocd.c is no longer needed and can
      be removed.

76d4c9f592 freertos: Refactor port_systick
This commit refactors port_systick.c so that all ports (RISC-V vs Xtensa) of
all FreeRTOS implementations (IDF vs Amazon SMP FreeRTOS) use the same set of
tick interrupt functions. Thus, these funcitons are now common:

- vPortSetupTimer() to setup the tick interrupt's timer
- xPortSysTickHandler() that is called on each tick interrupt

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.

0574e63e6f freertos: Add linker fragments for common functions
This commit adds a separate linker fragment file "linker_common.lf" for the
functions in "port_common.c". The placement rules are now clearly specified
inside the linker fragment file.
