feat(lib/psa): mock PSA APIs
Introduce PLAT_RSS_NOT_SUPPORTED build config to provide a mocked version of PSA APIs. The goal is to test the RSS backend based measured boot and attestation token request integration on such a platform (AEM FVP) where RSS is otherwise unsupported. The mocked PSA API version does not send a request to the RSS, it only returns with success and hard-coded values.
