Create a specific file for helper functions that are related to the PSA API. The reason for a separate file is so that it can include <psa/crypto.h>, without forcing this header inclusion into every test suite. In this commit, psa_helpers.function doesn't need psa/crypto.h yet, but this will be the case in a subsequent commit. Move PSA_ASSERT to psa_helpers.function, since that's the sort of things it's for. Include "psa_helpers.function" from the PSA crypto tests. In the ITS test, don't include "psa_helpers". The ITS tests are meant to stand alone from the rest of the library.
