Support direct comparison (git diff a..b) as well merge comparison (a...b) (#16635)

This PR changes the compare page to make the "..." in the between branches a clickable
link. This changes the comparison type from "..." to "..". Similarly it makes the
initial compare icon clickable to switch the head and base branches.
