This patch addresses review comments with regards to style of
`mbedtls_mpi_mod_modulus_setup/free()`.
It also removes a test check which was triggering a use-after-free.

data's lifecycle.

This patch updates the `mbedtls_mpi_mod_modulus_setup/free()`
methods to precalculate mm and rr(Montgomery const squared) during
setup and zeroize it during free.
A static `set_mont_const_square()` is added to manage the memory allocation
and parameter checking before invoking the
`mbedtls_mpi_core_get_mont_r2_unsafe()`

We think we're likely to change these macros. So make them *only* for
internal use, not just "mostly".

curves.pl, depends-hashes.pl, key-exchanges.pl and depends-pkalgs.pl are now superseded by depends.py.
Update all references to them accordingly.

It's not needed as a feature. It gets reenabled automatically in
build_info.h like pk_write and pk_parse, but that's an implementation
detail.

In the PSK exchange modes extension declare first
PSK ephemeral if we support both PSK ephemeral
and PSK. This is aligned with our implementation
giving precedence to PSK ephemeral over pure PSK
and improve compatibility with GnuTLS.

This patch moves the following tests to test_suite_bignum_core:

'mbedtls_mpi_core_get_mont_R2_unsafe' aligns const
keyword to match the style of the rest of the module.
Documentation is also updated to remove
`MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED`.

This patch adds the test for the method calculating the RR. The input/expected
data are generated manually using the following Python3 snippet:
~~~~~
import math
title="mpi_get_montgomery_constant_unsafe"
tt = title + " #{}"
in_data = [ "0f", ... ]
def limb_no(number, bil=64):
return int(math.ceil(int.bit_length(number)/(bil * 1.0)))
def calc_rr(number, bil=64 ):
return '{:x}'.format(pow(pow(2, limb_no(number, bil) * bil), 2, number))
def calc_rr_str(number, prefix=""):
rr64 = calc_rr(number)
rr32 = calc_rr(number, bil=32)
return '{}:"{:x}":"{}":"{}"'.format(prefix,number, rr32, rr64)
print("\n\n".join(["{}\n{}".format(tt.format(in_data.index(v)+1), calc_rr_str(int(v,base=16), title)) for v in in_data]))
