[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

Test Bugfix for uxTaskGetSystemState where getting system state immediately after creating
