backface-visibility:hidden should create a stacking context and containing
block.

Reviewed by Simon Fraser.
As of https://github.com/w3c/csswg-drafts/pull/9348, backface-visibility:hidden
should create a containing block and stacking context, if the element
participates in a 3D rendering context.
This adds a new preference for this change (currently disabled, until other
engines are ready to ship the change), and makes the code changes.
It also removes old WPTs that relied on the previous behaviour, and replaces
them with new ones testing the new spec.
