LibWeb: Don't generate ::before/::after for BR elements

Browse source 
We shouldn't be putting generated pseudo elements inside elements that
can't have children in the first place.

This patch fixes two issues:
- We stop generating pseudo elements for layout nodes that can't have
  children anyway.
- We mark Layout::BreakNode as not being able to have children.
