(This is a merge of http://go/wvgerrit/78105) The Widevine Android CDM should not allow itself to be instantiated without an app package name, as this breaks SPOID protection. Unfortunately, pathways exist prior to Android Q that allow this to happen, and we cannot break these devices by changing the behavior now. As such, we will only refuse to allow instantiation without an app package name on devices first launched with Q and later. This change also migrates the WVDrmFactory and its tests away from explicitly naming friend classes for individual test, in favor of the now-recommended "test peer" pattern. Bug: 65680731 Test: libwvdrmengine_hidl_test Test: CTS NativeMediaDrmClearkeyTest Change-Id: Icccd1d8b9972ef6ad7e5b0dbf2d37ec987656385
