[iOS] Enable PageCache backing store clearing optimization for WebKit2.
<https://webkit.org/b/154712>
Reviewed by Anders Carlsson.
We had an optimization for iOS where we'd tear down the compositing tree for
pages in the page cache, to save memory, but we were only enabling it when
instantiating a WebKit1 web view.
This patch enables the optimization for WebKit2 as well.
