Image Claims: minimum layout shift on desktop layout
## Issue
6068

## Change
Lock all images to fit a 16:9 container. We have implemented 'ZoomableImg', so no reason in trying to display in full size.

This reduces CLS from 0.4xx to 0.01x.

## Flaws
CLS could probably be zero if not for the spinner shifting things slightly. Also, mobile CLS is 0.07.

The troublesome part in this PR is that FileRenderInitiator, FileRender and their subcomponents are broken apart and it's hard to synchronize their visibility and size. There are time gaps where none of them are visible, etc.

This PR only tackles the major part (most bang for buck), which is the elimination of variable height of the rendered image.

## Aside
I think `claimIsMine` is unused, so don't waste time requesting it.

// - Display the button when '.vjs-touch-overlay' is displayed. However,
// the 'controlslist' attribute hack that was used to do this results in the
// button staying displayed without a fade-out timer.
// (3) Ideally, we should sync the '.vjs-touch-overlay' visibility with the
// cast button, similar to how to controlBar's visibility is synced above.
// But I have no idea how to grab the sibling '.show-play-toggle' into the
// css logic.
// (4) So, this is the best that I can come up with: Whenever user is idle,
// the button goes away. The only downside I know is the scenario of
// "overlay is up and video is paused, but button goes away due to idle".
// The user just needs to re-tap any empty space on the overlay to get the
// Cast button again.
