Details

According to the MediaKey.setServerCertificate spec [1] we should resolve with `false` if "If the Key System implementation represented by this object's cdm implementation value does not support server certificates". All other failures are represented by rejecting with an exception. Widevine supports setServerCertificate() but ClearKey does not. However ClearKey (on desktop) isn't following the spec; it's rejecting with NotSupportedError [2], so we should check into ChromiumCDMProxy::SetServerCertificate(). We could also have something in MediaKeySystemAccess.cpp to denote which keysystems we expect to support setServerCertfificate, and check that in ChromiumCDMProxy::SetServerCertificate().
