Bug 1848357 - Remove PaintWhileInterruptingJSNoOp(). r=mconley

Browse Source 
This should not be needed anymore. We no longer need to "ack" an epoch,
since there's no epoch.

Make the logic to trigger a paint and request composite a bit more
generic. That doesn't change behavior right now, because our visibility
state is tied to mRenderLayers, but without this change setting
renderLayers = true on a display: none iframe will trigger a useless
paint after bug 1847584.
