Declare a psa_key_file_id_t layout with an owner field
Declare the owner as psa_key_owner_id_t, of which an implementation
must be provided separately.
Make this a configuration option
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER, to make the conditional
compilation flow easier to follow. Declare it in config.h to
pacify check_names.sh.
Support for a specific implementation of psa_key_owner_id_t in storage
backends will come in a subsequent commit.
