The sequence of calls starts-update-starts-update-finish is not a
guaranteed valid way to abort an operation and start a new one. Our
software implementation just happens to support it, but alt
implementations may very well not support it.

The changed logic is to try a sign-message driver (opaque or transparent);
if there isn't one, fallback to builtin sofware and do the hashing,
then try a sign-hash driver. This will enable to the opaque driver
to fallback to software.

To avoid code duplication of the old-style SE interface usage
call psa_driver_wrapper_sign/verify_hash function instead of
the direct internal functions.

Update the mbedtls_test_psa_exercise_key to handle and use
PSA_KEY_USAGE_SIGN_MESSAGE and PSA_KEY_USAGE_VERIFY_MESSAGE key policies.
Add new tests for PSA_KEY_USAGE_SIGN_MESSAGE and PSA_KEY_USAGE_VERIFY_MESSAGE
policies.

Modify function and test case names that testing psa_sign_hash and
psa_verify_hash funtions to be less confusing with the newly introduced
function and test case names which tests psa_sign_message and
psa_verify_message functions.

Use common funtion for psa_sign_hash and psa_sign_message and one for
psa_verify_hash and psa_verify_message to unify them.

Since they became equivalent after moving the is_sign checking back to
the PSA core, they're now redundant, and the generic mac_setup function
can just be called directly.

Since a valid mac operation context would guarantee that the stored
mac size is >= 4, it wasn't immediately obvious that the zero-length
check is meant for static analyzers and a bit of robustness.
