Add more tracing for DXGI mapping and update tracing tests to detect it

The test tries to check that all the pieces of the GPU accelerated video capture are working. JS code checks that the video is OK, but it can't figure out if it was accelerated or not. So we check in traces that correct code paths, not the fallbacks, are taken. The issue was that this code path was valid but not expected in the test.
