c7328f1cc0 freertos: Fix race condition returning incorrect TCB on unpinned tasks
Noted as a problem with thread local storage returning a different task's
pointers, but some other were APIs also accessing current task unsafely.

f7b859ac84 freertos: Fix race condition using vTaskDelete() cross-core causing resource leak
Causes test added in parent commit to pass.

This race happens if the deleted task is running on the other CPU,
and is already spinning in a critical section waiting for xTaskQueueMutex
because it's about to be blocked for a resource.

The "deleted" task would end up blocked, possibly indefinitely, and
never actually deleted or its resources cleaned up by the idle tasks.

Details:

vTaskDelete() adds the target task to the xTasksWaitingTermination list,
expecting it to be yielded off CPU and then cleaned up later. However as soon as
vTaskDelete() releases xTaskQueueMutex, the target task runs and moves itself to the
xDelayedTaskList1. Because interrupts are already disabled on that CPU,
the "yield" to the other CPU sent by the vTaskDelete() comes afterward so
doesn't help.

9c73b80ee0 freertos: Increase minimum task stack size when stack smashing checker is enabled
Fixes issue with DPORT init task, this task uses minimum stack size and may not be
enough if stack smashing detection is set to Overall mode.

Also reworks the way we calculate minimum stack to allow for adding multiple
contributing factors.

61b70c50a4 freertos: Use the standard assert() function for configASSERT
Unless the option for "assert and keep running" is enabled.

This means that silent asserts now work for FreeRTOS, and disabling asserts
now also disables them in FreeRTOS without needing a separate config change.

78a94dbb6c freertos: Fix delay between interrupt request and trigger on RISC-V
NOP instructions have been added in order to prevent the code
from executing code it shouldn't execute. This is due to a delay
between the moment an interrupt is requested and the moment it
is fired. It only happens on RISC-V SoC.

d294ac381f freertos: fix errors reported by PVS-Studio
Removed leftover code-paths that were never taken. Upstream freertos uses
vTaskSuspendAll() and xTaskResumeAll(), and therefor check if the task already
yielded.

In the IDF port of freertos we use critcal sections instead, so xAlreadyYielded
will never be set.

Partially addresses https://github.com/espressif/esp-idf/issues/6440
