Move media::HDRMetadata, media::DisplayHelper to ui/gl/

We need to pass HDRMetadata to SwapChainPresenter which needs proper
metadata to set video processor. Moving media::HDRMetadata to ui/gl/ is
a prepared work for that.
This CL also move media::DisplayHelper to ui/gl/. Since it only provide
functions related with HDRMetadata, this CL renames it to
HDRMetadataHelper.
