Create PSA-specific helper function file 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.

Rename psa_helpers.function to psa_crypto_helpers.h This file isn't like the other .function files: it isn't concatenated by a separate preprocessing script, but included via C preprocessing. Rename this file to .h. This isn't a normal C header, because it defines auxiliary functions. But the functions aren't big and we only have one compilation unit per executable, so this is good enough for what we're doing.

New macro PSA_DONE for a clean PSA shutdown The new macro PSA_DONE calls mbedtls_psa_crypto_free, but before that, it checks that no key slots are in use. The goal is to allow tests to verify that functions like psa_close_key properly mark slots as unused, and more generally to detect key slot leaks. We call mbedtls_psa_crypto_free at the end of each test case, which could mask a bug whereby slots are not freed when they should be, but their content is correctly reclaimed by mbedtls_psa_crypto_free.
