[UnifiedPDF] Occasionally, PDF is stuck displaying low-res tiles when
switching tabs in Safari

Reviewed by Tim Horton.
We drop high-res tiles due to background tile purging, but do not get
them back when switching back to a Safari tab displaying a PDF. Since
this only reproduces with asynchronous drawing enabled for the contents
layer, this patch disables asynchronous drawing for said layer. A more
"correct" fix is tracked by https://webkit.org/b/274387.
