[ Merge of http://go/wvgerrit/148552 ] Extended the CDM layer to report OEMCrypto's watermarking support. The reporting of watermarking comes in three (3) mechanisms: 1) ClientCapabilities in license requests 2) CryptoSession metrics when queried to OEMCrypto 3) String property query by apps If OEMCrypto implementents OEMCrypto_GetWatermarkingSupport(), then the reported watermarking support by the CDM will match that of OEMCrypto. If OEMCrypto does not implement OEMCrypto_GetWatermarkingSupport() or an error occurs, it is assumed that OEMCrypto does not support watermarking, and the CDM will report "Not Supported".
