[ Merge of http://go/wvgerrit/71326 ] Nonce flood, frame size, session and system invalidation errors will now bubble up to the app. OEMCrypto v15 returns OEMCrypto_ERROR_BUFFER_TOO_LARGE, OEMCrypto_ERROR_SESSION_LOST_STATE, OEMCrypto_ERROR_SYSTEM_INVALIDATED and a variety of nonce errors. These will be reported to HIDL as OUTPUT_TOO_LARGE_ERROR, ERROR_DRM_SESSION_LOST_STATE, ERROR_DRM_INVALID_STATE and ERROR_DRM_RESOURCE_CONTENTION. Bug: 120572706 Test: Unit/Integration tests Change-Id: Ida177300046327ce81592a273028ef6c3a0d9fd9
