[LayoutNG] Remove one NGConstraintSpace constructor, mark others for removal.

Once the builder is added only the:
NGConstraintSpace(NGWritingMode, NGDirection, NGPhysicalConstraintSpace*)

should remain, this mirrors the NGFragment constructor which is just a "view"
on top of the NGPhysicalFragment.

This mirrors:
NGFragment(NGWritingMode, NGDirection, NGPhysicalFragment*)
