[UnifiedPDF] Make a background layers for each PDF page
https://bugs.webkit.org/show_bug.cgi?id=268834
<rdar://problem/122399196>
Reviewed by Tim Horton.
When we start drawing PDF off the main thread, we'll need to have
synchronously-drawn
boxes for where the pages will be. We can do that by making a small layer
hierarchy
per page consisting of layers with no backing store, but just a white fill
color,
and shadows.
The PDF continues to be painted into m_contentsLayer, which is higher in
z-order than
the collection of page background layers.
