Add Maybe<gfx::HDRMetadata> mHDRMetadata to PlanarYCbCrData and the corresponding HDRMetadata? hdrMetadata field to the YCbCrDescriptor IPC struct. Wire it through SetVideoDataToImage (copying from VideoInfo), CreateForYCbCr, and the SharedPlanarYCbCrImage path in ImageContainer. This is the media-side plumbing prerequisite that allows HDR metadata to reach WebRender for software-decoded video paths. Differential Revision: https://phabricator.services.mozilla.com/D296260
