Changes between FreeRTOS V10.4.4 and FreeRTOS V10.4.5 released September 10 2021

 + Introduce configRUN_TIME_COUNTER_TYPE which enables developers to define
   the type used to hold run time statistic counters. Defaults to uint32_t
   for backward compatibility. #define configRUN_TIME_COUNTER_TYPE to a type
   (for example, uint64_t) in FreeRTOSConfig.h to override the default.
 + Introduce ulTaskGetIdleRunTimePercent() to complement the pre-existing
   ulTaskGetIdleRunTimeCounter(). Whereas the pre-existing function returns
   the raw run time counter value, the new function returns the percentage of
   the entire run time consumed by the idle task. Note the amount of idle
   time is only a good measure of the slack time in a system if there are no
   other tasks executing at the idle priority, tickless idle is not used, and
   configIDLE_SHOULD_YIELD is set to 0.
 + ARMv8-M secure-side port:  Tasks that call secure functions from the
   non-secure side of an ARMv8-M MCU (ARM Cortex-M23 and Cortex-M33) have two
   contexts – one on the non-secure side and one on the secure-side. Previous
   versions of the FreeRTOS ARMv8-M secure-side ports allocated the structures
   that reference secure-side contexts at run time.  Now the structures are
   allocated statically at compile time.  The change necessitates the
   introduction of the secureconfigMAX_SECURE_CONTEXTS configuration constant,
   which sets the number of statically allocated secure contexts.
   secureconfigMAX_SECURE_CONTEXTS defaults to 8 if left undefined.
   Applications that only use FreeRTOS code on the non-secure side, such as
   those running third-party code on the secure side, are not affected by
   this change.
