Factory::DoesBackendSupportDataDrawtarget already fulfills the same purpose and we should use that instead, as imgFrame is the only user of the former API. It has the added bonus of allowing us to use shared surfaces on Linux with WebRender, and using volatile surfaces on Windows when D2D is disabled.
