Revert back to UIKit for the presentation of the timeline media preview. (#3719)

* Revert back to UIKit for the presentation of the timeline media preview.

* Fix a presentation issue where the media is clipped until the animation finishes.

* Workaround for the preview controller replacing the info button when swiping.

* Use a self-sizing detent on the media info sheet.
