REGRESSION (280917@main): Crash when omitting a visibility:hidden RenderLayer
from the z-order tree.
https://bugs.webkit.org/show_bug.cgi?id=277115
<rdar://132358145>
Reviewed by Simon Fraser.
If we decide we can newly omit a RenderLayer in the z-order tree due to not
being visible, we need to also notify the compositor that these layers are
'gone' so that state can be updated correctly.
