Currently PSA mac backends can only implement psa_mac_compute() from
the PSA crypto API, but not psa_mac_verify() and the associated
multi-part functions.
Extend the location and algorithm dispatchers to connect the above
PSA API functions to suitable backends. Also extend the MAC backend
API to allow backends to implement those additional functions. Due
to a design issue with the SE backend API (context size is dynamic,
thus requiring a memory allocation) only psa_mac_verify() can be
accelerated by SE backends.

The PSA crypto specification states that when creating keys,
the usage flags PSA_KEY_USAGE_SIGN_HASH/PSA_KEY_USAGE_VERIFY_HASH
automatically set the usage flags
PSA_KEY_USAGE_SIGN_MESSAGE/PSA_KEY_USAGE_VERIFY_MESSAGE on the key.
