Gilles Peskine 069346cdab New test suite for not-supported cases: key creation (import, generate)
To start with, test that key creation fails as intended when the key
type is not supported. This commit only covers psa_import_key and
psa_generate_key. A follow-up will cover psa_key_derivation_output_key.

My primary intent in creating this new test suite is to automatically
generate test cases by enumerating the key types and algorithms that
the library supports. But this commit only adds a few manually written
test cases, to get the ball rolling.

Move the relevant test cases of test_suite_psa_crypto.data that only
depend on generic knowledge about the API. Keep test cases that depend
more closely on the implementation, such as tests of non-supported key
sizes, in test_suite_psa_crypto.data.
