Accelerated animations on ::backdrop shouldn't affect <dialog> (backdrop-animate-002.html fails)
https://bugs.webkit.org/show_bug.cgi?id=230008
<rdar://problem/82975766>

Reviewed by Simon Fraser and Tim Nguyen.

Source/WebCore:

We did not know how to access the ::backdrop renderer when running accelerated animations. To do so we now
implement full support to access the renderer for known pseudo-elements on Styleable with a new renderer()
method, including ::backdrop. We also make Styleable::fromRenderer() aware of ::backdrop such that the various
call sites for this function that deal with accelerated transform animations access the right element.
