Do not reorder overflow overlay layers for hidden layers

https://crrev.com/1409257 omitted visibility: hidden layers from
z-index lists. This introduced a bug because overflow overlay
re-ordering [1] could be set up to paint a reordered overlay layer
after a visibility: hidden layer which never paints. This patch also
skips visibility hidden layers from overflow overlay reordering.
