(This is a merge of http://go/wvgerrit/25580) While writing fixes for b/36660726, b/34716264, and b/36065223, it became clear that having the logic that checks whether the device supports SPOIDs embedded inside WVDrmPlugin was complicating its code and inhibiting testing of the class. By moving this check into the code that instantiates WVDrmPlugin, the result of the calculation can be independently tested while the tests for WVDrmPlugin can put it in whatever state they need for the sake of unit testing. As a consequence of this, the check on retrieving the "deviceUniqueId" byte array property, which was removed when SPOIDs were implemented, can be reinstated. Bug: 36660726 Bug: 34716264 Bug: 36065223 Test: libwvdrmdrmplugin_hidl_test & libwvdrmengine_hidl_test Change-Id: I961d2ee42bbdc42f0c324e36d9a74ac92205a437
