LibWeb: Store layout box model metrics as floats

Browse source 
Instead of storing them as CSS::Lengths, we now store the resolved
values for margin/padding/border/offset top/right/bottom/left with
each Layout::NodeWithStyleAndBoxModelMetrics.

This simplifies a lot of code since it's no longer necessary to
resolve values before using them.
