Make it possible to query scrollbar pseudo-style without having a scrollbar
https://bugs.webkit.org/show_bug.cgi?id=203174

Reviewed by Tim Horton.

A future patch needs the ability to query scrollbar pseudo-style without having
a scrollbar, and it was ugly to pass a live RenderScrollbar into CSS style resolution
functions. Instead, pass in a pure-data object that has information about the scrollbar.
