9d63e1da4a New Task Watchdog API (Revert of Revert)
This commit reverts the revert on the new task watchdog API. It also
fixes the following bug which caused the reversion.

- sdkconfig TASK_WDT_TIMEOUT_S has been reverted from the unit of ms back to the
unit of seconds. Fixes bug where projects using the new API without rebuilding sdkconfig
would cause the old default value of 5 to be interpreted in ms.

This commit also adds the following features to the task watchdog

- Updated idle hook registration to be compatible with dual core hooks

- Updated dual core hooks to support deregistration for cpu

- Legacy mode has been removed and esp_task_wdt_feed() is now replaced by
  esp_task_wdt_reset().  esp_task_wdt_feed() is deprecated

- Idle hooks to reset are now registered/deregistered when the idle tasks are
  added/deleted from the Task Watchdog instead of at Task Watchdog init/deinit

- Updated example

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

ae9041ab71 esp32: Fix task watchdog timer triggering issues TW#14794
The two task watchdog timer bugs are as follows...
1) If only a single task existed on the wdt task list, and esp_task_wdt_feed()
was only called once, the watchdog triggers but fails to print task name
2) If a single task already exists on the task wdt list, and another task calls
esp_task_wdt_feed() once, the watchdog fails to trigger

Problem stemmed from the loop responsible for resetting the watchdog timer
having incorrect loop parameters. The loop failed to traverse the full length
of the task wdt list

to be marked specifically as having a handler that's all in IRAM.
