UnifiedPDF: PDF in embed/object/iframe repaint constantly when the main frame
scrolls

Reviewed by Simon Fraser.
* Source/WebKit/WebProcess/Plugins/PDF/UnifiedPDF/UnifiedPDFPlugin.mm:
(WebKit::UnifiedPDFPlugin::geometryDidChange):
Avoid calling updateLayout() (which is a full repaint and incredibly expensive)
every time the plugin-to-root-view transform changes; we only need to rebuild
if the size of the plugin changes.
This avoids constant repaints when scrolling the main frame with an embedded
PDF.
