vpr: Enable graphics animation using ezgl

Using new ezgl support, we now re-draw the screen whenever update_screen()
is called. This update the user interface based on the current
implementation state (e.g. placement/routing). This is similar to how
the old easygl graphics operated.

However with ezgl we now also support user interaction between
update_screen() calls, allowing users to click/highlight/toggle features
even during minor screen updates (which don't pause VPR by going into
the graphics event loop by default).
