and refactors the tests. Documentation has also been updated.

This patch is inverting the input type checking logic in the method,
in order to ensure that residue < modulus.

This patch adds the following tests for the high levet IO api:
* mpi_mod_io_neg
* mpi_mod_io
Manually generated test data has also been included.

psa_cipher_encrypt() and psa_cipher_decrypt() sometimes add a zero offset to
a null pointer when the cipher does not use an IV. This is undefined
behavior, although it works as naively expected on most platforms. This
can cause a crash with modern Clang+ASan (depending on compiler optimizations).

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.

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.

- external errors are now checked in the specified point. If the
same error happens in another line, then this is not valid and
the test fails
- fixed some inconsistency in which injected error codes were not
taken from the data file. Now all the expected error code are
read from the data file
- added a couple of defines to shrink the code

As for ecjpake_setup(), now the test function can handle:
- "external" errors, through parameters set by the data file
- "internal" ones, through enums which inject ad-hoc failures
Similarly also ecjpake_rounds() can handle both type of errors,
but right now there's no erroneous case in the associated ".data"
file.
In both cases, after an error the current test is terminated.
