Switch from the direct use of slot numbers to handles allocated by psa_allocate_key. The general principle for each function is: * Change `psa_key_slot_t slot` to `psa_key_handle_t handle` or `psa_key_id_t key_id` depending on whether it's used as a handle to an open slot or as a persistent name for a key. * Call psa_create_key() before using a slot, instead of calling psa_set_key_lifetime to make a slot persistent. Remove the unit test persistent_key_is_configurable which is no longer relevant.
