esp32: mpi: add workaround for data corruption issue observed with IDF 5.x toolchain
This fix adds a workaround to disable compiler optimization flag "-ftree-loop-distribute-patterns"
for `mpi_to_mem_block` routine. It was observed that compiler with release configuration was falling
back to `memset` call from ROM library causing an issue in correctly zero initializing MPI peripheral
block.

Please see following linked issue for more discussion and context on this issue.

c097e6bcab mbedtls: fix hardware MPI (bignum) related regression
In commit de22f3a4e5, combination of
hardware and software MPI (bignum) related approach was used to
work around chip (e.g. ESP32-C3) limitation of max 3072 bits support.

This was done using linker "--wrap" flag but since the relevant API is
being used in same translation (compilation unit), hardware mode was not
getting used in some cases (e.g., RSA key generation).

This commit modified internal mbedTLS API and makes software+hardware
combination deterministic.

de22f3a4e5 MbedTLS: Add software fallback implementation for exp mod
Add configuration option to fallback to software implementation
for exponential mod incase of hardware is not supporting it
for larger MPI value.

Usecase:
ESP32C3 only supports till RSA3072 in hardware. This config option
will help to support 4k certificates for WPA enterprise connection.

8bba348528 aes/sha/mpi: Bugfix a use of shared registers.
This commit resolves a blocking in esp_aes_block function.

Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.

Fix some related issue with shared using of AES SHA RSA accelerators.

961f59ff57 mbedtls: Don't unnecessarily grow the result of a hardware bignum operation
Avoids growing the result of hardware bignum operations
(particularly for multiplication)

Fixes bugs where some Elliptic Curve operations fail or corrupt memory,
as they assume length of the number is never greater than the number of
non-zero limbs.

Includes some general refactoring to standardize terminology.

Closes https://github.com/espressif/esp-idf/issues/1556

Fixes TW12984

Adds test cases for both these issues.

8f80cc733d soc: Change DPORT access
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.

The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.

79646f41b5 Fixes for stdlib.h inclusion
Refs:
http://esp32.com/viewtopic.php?f=13&t=550
http://esp32.com/viewtopic.php?f=13&t=551

rmt.c should include stdlib.h for malloc, esp_bignum,c &
https_request_main.c for abort().

FreeRTOSConfig.h is only including stdlib if
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION is set. However, it is
included for abort() so needs to be included whenever
CONFIG_FREERTOS_ASSERT_FAIL_ABORT is set.

This change includes unconditionally in FreeRTOSConfig.h. This is to
avoid this kind of bug where compiler errors are dependent on config. I
suggest we don't change this to be more selective until we have 'make
randomconfig' style tests in CI.
