[UnifiedPDF] Plugin should delegate releasing page previews to the
presentation controller
https://bugs.webkit.org/show_bug.cgi?id=277049
rdar://132443805
Reviewed by Sammy Gill.
Following 281282@main, the PDF plugin performs a no-op when it gets
forwarded a memory pressure warning from the web page. In this patch, we
restore the previous behavior of having the async renderer clean up page
previews upon a memory pressure warning. We facilitate this behavior by
having the plugin delegate `::releaseMemory` to the presentation
controller, which simply forwards the duty to the async renderer.
