Add overline option for Table rows (#5637)

Browse Source 
* Closes no issue, I just needed this for an app and figured it could be
useful.
* [x] I have followed the instructions in the PR template

This PR adds an `overline` option for `egui_extras::TableRow`, which is
useful for visually grouping rows. The overline consumes no layout
space.

A screenshot of the demo app, showing every 7th row getting an overline.
