hgTrackUi: add "Hide all tracks" and "Show all tracks" buttons to the superTrack page, and drop "Apply to all visible tracks". The two new buttons cover the two things people actually do on a container page. "Show all tracks" asks for pack and falls back to full for tracks that have no pack, i.e. signal tracks, so a container of bigWigs comes up in full. The old "Apply to all visible tracks" button needed two sentences of help text to distinguish it from "Apply to all tracks" and is gone; the dropdown plus "Apply to all tracks" still covers dense and squish. refs #38281
