Cleanup: Move timeline_exporer js out of html file into js.
https://bugs.webkit.org/show_bug.cgi?id=112188

Reviewed by Dirk Pranke.

Moves the javascript out of the html file and into a new js file.
This follows the format of flakiness_dashboard.{html|js}.

Also moves code from dashboard_base that is used only by this one
dashboard, and makes it private to the dashboard.
