91a2aabb86 Refactor mpi_core_sub tests to use arch_split
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.

6f949ea67b New constant-flow function mbedtls_mpi_core_uint_le_mpi
Compare a single-limb MPI with a multi-limb MPI. This is rather ad hoc, but
will be useful for mbedtls_mpi_core_random.

0f0d1e88a2 mpi_core_exp_mod: add unit tests
The test cases aim to mirror the legacy function, but needed the some
cases to be removed because:

- Null representation is not valid in core
- There are no negative numbers in core
- Bignum core doesn't do parameter checking and there are no promises for
  even N

The _size variant of the test has been removed as bignum core doesn't do
parameter checking and there is no promises for inputs that are larger
than MBEDTLS_MPI_MAX_SIZE.

59cbd1be27 Make mbedtls_mpi_core_ct_uint_table_lookup static
Now that we have a function that calls
mbedtls_mpi_core_ct_uint_table_lookup(), the compiler won't complain if
we make it static.

5933f691a2 Add merge slots to Bignum files
Legacy Bignum is excluded as it doesn't get regular extensions like new
ones.

Each slot uses comments of their respective filetype. Since .data files
don't have a syntax for comments, dummy test cases are used. (These test
cases will never be executed and no noise will be added to tests.)

5980f2bd36 Implement mbedtls_mpi_core_fill_random
Turn mpi_fill_random_internal() into mbedtls_mpi_core_fill_random(). It
had basically the right code except for how X is passed to the function.
