MediaCapabilities: check gpu video acceleration for powerEfficient

Feature disabled by default. Enable with command line:
--enable-features=MediaCapabilitiesQueryGpuFactories

Historically info.powerEfficient was determined by the
VideoDecodePerfHistory DB. This patch instead queries the GpuFactories
(proxy for hw decode) for to ask the question directly.

The critical difference is that the DB requires some past data to
be correct, while GpuFactories will know the answer without ever having
played a video.
