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.

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).

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.

The random-in-nrange test code has auxiliary functions that are common to all
the interfaces (core, mod_raw (upcoming), mod (upcoming), legacy), and does
some differential testing to check that all the layers consume the RNG in
the saame way. Test them all in the same test suite.

Test some cases where mbedtls_mpi_core_random() or mbedtls_mpi_random()
should return MBEDTLS_ERR_MPI_NOT_ACCEPTABLE. These test cases use a very
small range that makes the NOT_ACCEPTABLE case likely. The test code uses a
deterministic RNG whose implementation is in the test framework, so we know
that the tests will pass reproducibly unless the implementation the test
framework changes.

The test function mpi_random_many() is the main function for testing the
get-random-in-range function. It validates that the random generator's
output is within the desired range, and performs some basic statistical
checks including checking that small ranges are covered exhaustively.
Switch this function from testing mbedtls_mpi_random() to testing
mbedtls_mpi_core_random(). This does not reduce the test coverage of
mbedtls_mpi_random() because the same properties are now validated
indirectly via mpi_random_values() which checks that mbedtls_mpi_random()
and mbedtls_mpi_core_random() produce identical values for identical inputs.
As of this commit, mpi_random_many() still uses some legacy mpi functions
internally because the corresponding functions don't exist yet in core.

For good cases, test that mbedtls_mpi_random() produces the same output as
mbedtls_mpi_core_random().

Compare a single-limb MPI with a multi-limb MPI. This is rather ad hoc, but
will be useful for mbedtls_mpi_core_random.
