configs: Update example PSA config
Our default configuration file, include/mbedtls/config.h, should always
match configs/config-psa-crypto.h. It had gotten out of sync, so put it
back into sync.

+ * This is only meaningful when building the library as part of a

+ * an implementation of the type psa_key_owner_id_t and a translation
+ * from psa_key_file_id_t to file name in all the storage backends that
+ * you wish to support.
+ *
+ * Note that this option is meant for internal use only and may be removed
