Add recoverable errors

Browse Source 
[ 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.
