LibWeb: Add basic support for position:fixed

Browse source 
Fixed position elements have the ICB as their containing block.
The magic of fixed positioning is implemented at the rendering stage,
where we temporarily translate painting by the current scroll offset.

Note that "absolutely positioned" includes both position:absolute
and position:fixed.
