Remove psa_crypto_storage_backend.h
Since there is now a single storage backend, we don't need a backend interface. Make the functions that were declared in psa_crypto_storage_backend.h and are now both defined and used in psa_crypto_storage.c static, except for psa_is_key_present_in_storage which is used by the gray-box tests and is now declared in psa_crypto_storage.h.
