Simplify split diff view generation and remove JS dependency () ()
Backport 

Gitea has relied on some slow JS code to match up added and deleted lines on the
diff pages. This can cause a considerable slow down on large diff pages.

This PR makes a small change meaning that the matching up can occur much more simply.

Partial fix
