Enumerate metadata test functions explicitly

When gathering test cases from test_suite_psa_crypto_metadata, look up
the test function explicitly. This way test_psa_constant_names will
error out if we add a new test function that needs coverage here.

This change highlights an omission in the previous version:
asymmetric_signature_wildcard was silently ignored as a source of
algorithm expressions to test. Fix that.
