[LayoutNG] Cleanup visual overflow computations

This patch cleans up visual overflow computations in:
1. Use type-safe geometry classes. NGPhysicalOffsetRect is added.
2. Add conversion functions for LayoutUnit to type-safe geometry
   classes.
3. LocalVisualRect() turned out not to include its children.
   Matched to the definition and separated ContentsVisualRect().
4. Removed NGPhysicalFragment::LocalVisualRect() and its storage.
   NGPhysicalBoxFragment has the storage, but other types are
   assumed to be cheap and compute on the fly.
5. Removed NGPhysicalFragment::UpdateVisualRect(). Box fragments
   computes in NGFragmentBuilder.
6. With that, removed all virtual functions from NGPhysicalFragment.
