psa: Implement persistent keys

Browse Source 
Allow use of persistent keys, including configuring them, importing and
exporting them, and destroying them.

When getting a slot using psa_get_key_slot, there are 3 scenarios that
can occur if the keys lifetime is persistent:

1. Key type is PSA_KEY_TYPE_NONE, no persistent storage entry:
   -  The key slot is treated as a standard empty key slot
2. Key type is PSA_KEY_TYPE_NONE, persistent storage entry exists:
   -  Attempt to load the key from persistent storage
3. Key type is not PSA_KEY_TYPE_NONE:
   -  As checking persistent storage on every use of the key could
      be expensive, the persistent key is assumed to be saved in
      persistent storage, the in-memory key is continued to be used.

* psa_generator_import_key(). To open an existing persistent key, you must
* call this function with the correct lifetime value before using the slot
* for a cryptographic operation. Once a slot's lifetime has been set,
* the lifetime remains associated with the slot until a subsequent call to
* psa_set_key_lifetime(), until the key is wiped with psa_destroy_key or
* until the application terminates (or disconnects from the cryptography
* service, if the implementation offers such a possibility).
