Hide description header in tvOS video info right column

The right column is already dedicated to video info so the "Description"
label is redundant. Add an opt-out `showsHeader` parameter to
`TVScrollableDescription` (default true) and pass false from
`VideoInfoView`; the player overlay and channel view keep the header.
