8b56345e44 unit tests: fix queue registry test
In the queue registry test, start_sem is given twice to let both tasks
start the test. Each task takes start_sem, does some work, gives done_sem,
and goes on to wait for start_sem again.
It may happen that one task can grab start_sem, add queues to the
registry, give done_sem, then grab start_sem again, delete the queues
from the registry, and give done_sem again. At this point, main test
task takes done_sem twice and proceeds to verify that queues have been
added to the registry. But in fact, the first task has already deleted
its queues from the registry, and the second one might not have added
the queues yet. This causes test to fail.

This changes the test to use separate start semaphores for each task,
to avoid the race condition.

d1853dbbc0 FreeRTOS/make Queue Registry and Run Time Stats configurable
This commit makes the configQUEUE_REGISTRY_SIZE and
configGENERATE_RUN_TIME_STATS configurable in menuconfig.

- configQUEUE_REGISTRY_SIZE can now be set in menuconfig.
- The functions vQueueAddToRegistry() and vQueueUnregisterQueue() were made
  SMP compatbile
- pcQueueGetName() was backported from FreeRTOS v9.0.0
- Added test case for Queue Registry functions

- configGENERATE_RUN_TIME_STATS can now be enabled in menuconfig. CCOUNT or
  esp_timer can be selected as the FreeRTOS run time clock in menuconfig as
  well, although CCOUNT will overflow quickly.
- Run time stats collection (in vTaskSwitchContext) and generation (in
  uxTaskGetSystemState) have been made SMP compatible. Therefore
  vTaskGetRunTimeStats() now displays the run time usage of each task as a
  percentage of total runtime of both CPUs

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
