AnimEditors: Draw start/end frame ranges on all timelines by default

This uses the global scene range, with styling matching the sequencer's start/end
frame drawing.

(The graph editor's "drivers" mode is exempt, as that doesn't really display time
in a linear way, so the start/end frames don't apply)
