Traverse layers in update order

bug:8540150

Layers now require traversal in update order, as it will be child
first, then parent for layer-in-layer

Fixes issue with deferred layer playback not flushing in order, and
thus child not painting before parent

Also fixes DisplayList to only be cleared after flush in deferred list
