5ed8388f6b mbedtls: Add Montgomery exponentiation implementation (HAC 14.94)
It gave us a better performance of RSA operations. (2~11 times)

The old modexp implementation (Z = X ^ Y mod M) loaded all the data into
the hw registers and was waiting for completion, but due to
the hardware RSA implementation, the calculations always started with 4096 bit,
which took a lot of time.
Measurement results (measurements were made for keys: 2048, 3072 and 4096 bits)
(Old) - Sliding-window exponentiation (HAC 14.85):
keysize = 2048 bits
RSA key operation (performance): public [93206 us], private [280189 us]
keysize = 3072 bits
RSA key operation (performance): public [293614 us], private [858157 us]
 keysize = 4096 bits
RSA key operation (performance): public [653192 us], private [1912126 us]

Instead (Old) - Sliding-window exponentiation (HAC 14.85) was implemented
(New) - Montgomery exponentiation (HAC 14.94) which showed
better performance on private and public keys.
keysize = 2048 bits
RSA key operation (performance): public [14504 us], private [149456 us]
keysize = 3072 bits
RSA key operation (performance): public [35073 us], private [392743 us]
keysize = 4096 bits
RSA key operation (performance): public [58650 us], private [787186 us]

For this reason, the old implementation was removed
and the MBEDTLS_HARDWARE_MPI option was turned on by default.

Why the MPI_INTERRUPT option is removed:
the old implementation used calculations on the hardware and
it took a lot of time (10ms - 500ms). And in order not to stand idle
while waiting for completion, an interrupt option was added.
This made it possible to carry out other tasks during the calculation,
and this one to block. The new method is free from such a drawback and
the maximum duration of one RSA HW operation does not exceed 70us (usually 2-70 μs).
This option is no longer needed.

Closes: IDF-965

142e49f4cc unit-test-app: fix chip-specific sdkconfig options
DEFAULT_CPU_FREQ and ULP_COPROC_ENABLED options have chip-specific
names, and should be set in a chip-specific sdkconfig.defaults file.
This commit also changes the default CPU frequency for ESP32S2 unit
tests to 240 MHz.

037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

c1d101dd41 freertos/backport and test v9.0.0 functions
This commit backports the following features from FreeRTOS v9.0.0
- uxSemaphoreGetCount()
- vTimerSetTimerId(), xTimerGetPeriod(), xTimerGetExpiryTime()
- xTimerCreateStatic()
- xEventGroupCreateStatic()
- uxSemaphoreGetCount()

Functions backported previously
- xTaskCreateStatic()
- xQueueCreateStatic()
- xSemaphoreCreateBinaryStatic(), xSemaphoreCreateCountingStatic()
- xSemaphoreCreateMutexStatic(), xSemaphoreCreateRecursiveMutexStatic()
- pcQueueGetName()
- vTaskSetThreadLocalStoragePointer()
- pvTaskGetThreadLocalStoragePointer()

Unit tests were also written for the functions above (except for pcQueueGetName
which is tested in a separate Queue Registry MR). The original tlsp and del cb test case
was deleted and integrated into the test cases of this MR.

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
