The code had an earlier version. Update to the new seed that
mpi_core_random_basic has moved to.

mbedtls_mpi_mod_raw_random() and mbedtls_mpi_mod_random() were producing
output in the Montgomery representation, instead of obeying the
representation chosen in the modulus structure. Fix this.
Duplicate the test cases for mod-random output to have separate test cases
for each representation.

This wasn't reported by pylint due to a pylint bug (apparently):
`pylint A B` doesn't complain about an unused import in B if A happens to
import and use the same module, which happens to be the case when we run
pylint on the CI.

In the basic/XXX=core test cases, use odd upper bounds, because the mod
version of random() only supports odd upper bounds (the upper bound is a
modulus and the mod modules only support odd moduli).

When including <test/bignum_helpers.h>, the library/ directory now needs to
be on the include path.

Move bignum-related helper functions to their own files under tests/include
and tests/src. The primary motivation is that a subsequent commit will make
bignum_helpers.h include library/bignum*.h, but we want to be able to
include <test/helpers.h> without having the library directory on the include
path (we do this in some programs under programs/ intended for testing).

mpi_core_random_basic and mpi_random_values must generate the same random
sequences in order to get the expected test coverage (where we know we'll
hit certain numbers of retries). Facilitate this by defining the RNG seed
only once.
Fix the seed to explicitly list all 16 words of the key. This isn't strictly
required (missing initializer fields get the value zero), but it's clearer.

Tests are refactored to generate separate cases for 32-bit and 64-bit
limbs using arch_split. Duplicate arguments and branching in the test
function is removed.

This is not new, it had always been the case, just not documented.
Pointed out by depends.py pkalgs (again, now that restartable is part of
full).

muladd() (restartable or not) is only available when at least one short
weirstrass curve is enabled.
Found by depends.py curves (now that restartable is part of full).
Also, document that restartable only work for short weierstrass curves
(actually unrelated, but this made me think of that).

The previous commit declared that some tests cases in ssl-opt.sh depend
on USE_PSA being disabled, which is the right thing to do.
We had a check that forbade that - it was mainly meant to prevent
accidental re-introduction of such dependencies after we cleaned up a
number of cases where it was not warranted, but already at the time that
was controversial [1]. Now it's preventing us from doing the right
thing, so let's just remove it.

See also https://github.com/Mbed-TLS/mbedtls/pull/5907/ which also
removes this for a similar reason.

This fixes the two failures in test_suite_x509parse when both
ECP_RESTARTABLE and USE_PSA_CRYPTO are enabled.
The failure happened because the operation is dispatched to PSA when
restart is disabled (max_ops == 0).
Previously it was correct for this test function not to initialize PSA,
because it depends on ECP_RESTARTABLE which used to conflict with
USE_PSA_CRYPTO, but that's no longer the case.
