Added CDM support for Watermarking reporting.

[ 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".

Bug: 226443788
Test: run_x86_64_tests request_license_test and license_unittest
