Add support for RichMedia annotations
Render `/Subtype /RichMedia` annotations so embedded video and audio can
be played in the viewer.

The core layer parses the `RichMediaContent` dictionary to locate the
primary playable asset and its MIME type. The display layer overlays a
play button on the annotation's poster; clicking it swaps in a
`<video>`/`<audio>` element backed by a `blob:` URL. Presentation mode
lets events reach the media controls instead of advancing the page.

It fixes #2787.
