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

4fdaeb6b6e cmake: Add new compiler optimization levels definitions
Rename and add multiple kconfig compiler options. New compiler options
COMPILER_OPTIMIZATION_PERF and COMPILER_OPTIMIZATION_NONE have been added.
Optimize "Debug" and "Release" options to "Default" and "Size" respectively.
This commit also does the following:

- The COMPILER_OPTIMIZATION_PERF option introduced multiple bug.
This commit fixes those bugs.
- build.yml also updated to test for the new optimization options.

7f307423c1 newlib: Provide library name for ROM libc object files linked as PSRAM workarounds
Works around bug reported on forums where any source file ending in *lock.c or *creat.c
was being linked to IRAM.

https://esp32.com/viewtopic.php?f=13&t=8909&p=37362#p37362

Also moves all related functionality to newlib component.

769bd4a4af linker: When using section type attributes, create unique sections
* Prevents section type conflict errors if (say) const & non-const data
  is put into the same section (ie with DRAM_ATTR)
