616baa239d esp32: New Task Watchdog API
Legacy API of task watchdog used the same function esp_task_wdt_feed() to add
and feed a task. This caused issues of implicitly adding a task to the wdt list
if the function was used in shared code.

The new API introduces init, adding, feeding, deleting, deinit functions. Tasks
must now be explicitly added to the task watchdog using their handles. Deletion
must also be explicit using task handles. This resolves the issue of implicit
task additions to the task watchdog due to shared code calling
esp_task_wdt_feed().

Task watchdog is now fully configurable at runtime by calling the init and
deinit functions.

Also added functions to get the handles of idle tasks of the other core. This
helps when adding idle tasks to the watchdog at run time.

Configuring the task watchdog using menu config is still available, however
menu config will only result in calling the init and add functions for idle
tasks shortly after the scheduler starts.

Menu config also allows for using legacy behavior, however the legacy behavior
willcall the new API functions but with slight variations to make them legacy
compatible.

Documentation and example have also been updated

gcov_rtio.c headers updated to prevent error of freertos header files being
included in the wrong order.

Resolves issue TW#13265

6ab552a6ea docs: Added documentation for FreeRTOS SMP changes
Added documentation about the ESP-IDF changes to FreeRTOS.
The documentation covers changes to the following FreeRTOS aspects.

    - Task Creation
    - Affects on scheduling (Task skipping, scheduler suspension, tick synchronicity)
    - Critical sections and disabling interrupts
    - Thread Local Storage Pointers and deletion callbacks
    - Configuring ESP-IDF FreeRTOS

64bce3ce59 freertos: place uxTopUsedPriority into DRAM
When debugging crashes caused by flash cache access errors, OpenOCD may
request the value of uxTopUsedPriority when cache is disabled. Placing
it into IRAM to avoid an error in such case.

99a4b6b2db freertos: introduce CONFIG_FREERTOS_INTERRUPT_BACKTRACE

consistently: #if was used in one case, and #ifdef in another. This makes
the checks consistent, and also introduces a Kconfig option to enable
backtrace.

eb1b4f971b freertos: make sure xPortGetCoreID is placed into IRAM
In some cases, xPortGetCoreID was not inlined, and ended up in flash.
Since this function is used in many situations when cache is disabled,
that caused exceptions. Adding IRAM attribute to fix that.

ba8cd58b08 kconfig: Remove Wi-Fi on/off as a menuconfig option
This is no longer required since the functions automatically get
pulled in based on the usage. A quick summary of footprint
comparisions before and after these set of patches is shown below:

Hello-World: (simplified for readability)

For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly
the nvs_flash_init() function).

The size actually shrinks a bit, since the AP interface function
doesn't get pulled in.

8d43859b6a esp32: SEGGER SystemView Tracing Support
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

[871ec26f] Freertos:Bugfix uxTaskGetSystemState

Bug (github #12142) with uxTaskGetSystemState where
if called immediately after creating a bunch of tasks,
those tasks would be added twice into the TaskStatusArray.
Bug caused due to use old implementation using vTaskSuspendAll
which did not stop newly created task on other core from accessing the
read/waiting task lists whilst the list were being read by
uxTaskGetSystemState. Fixed bug by replacing vTaskSuspendAll
with taskENTER_CRITICAL and added test case for the bugfix

b9fc5ecf68 freertos: Fix crash when waking task on CPU1 with scheduler disabled
xPendingReadyList[1] was never initialised correctly, so if a task is added to this list (ie by xSemaphoreGiveFromISR()
or similar) while scheduler is disabled, then it causes a null pointer dereference.

Bug produces stack traces similar to:
