[DevTools] Add Play/Pause and Skip Controls to the Timeline (#34620)

Stacked on #34625.

This is a nice way to step through the timeline and simulate the visuals
on screen as you do it. It's also convenient to step through one at a
time, especially with the forwards button.

However, the secondary purpose of this is that it helps anchor the UI
visually as something like a timeline like in a video so that the
timeline itself becomes more identifiable.
