This makes all backends register the default queue at device initialization time, so that the same queue is returned by each call to GetDefaultQueue. All usages of CreateQueue are replaced by GetDefaultQueue except a couple ones that could use the queue initialized by DawnTest::SetUp. A deprecation warning mechanism is added so that users of Dawn can now that they should upgrade their usage of the API. It also comes with a backdoor so we can test that they are emitted. New DeprecatedAPITests are added that will contain tests for deprecated APIs, and will also check that deprecation warnings are produced. The special casing of GetDefaultQueue in the wire will be done in a follow-up CL to ease the review. It happens to work through the regular wire mechanisms at the moment but returns a different object on each GetDefaultQueue call.
