When building for the PSA crypto service (defined(PSA_CRYPTO_SECURE)), define psa_key_owner_id_t as int32_t, which is how a PSA platform encodes partition identity. Note that this only takes effect when the build option MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is active. Support this configuration in the ITS backend.
