Subject: [PATCH] Set HDR color info on FrameworkMuxer

Not setting the color info results in a missing "colr" box in the produced
container, under file/moov/trak/mdia/minf/stbl/stsd/hvc1. This means extractors
will not be able to find out the transcoded file is HDR.

In `Transformer`, this means it can't transcode this transcoded file, because
it currently relies on the container bearing HDR info to construct the
transcoding sample pipeline.

(cherry picked from commit d6c8e3a8aff07be5c184473826753047bf4b2387)
