Rework CB management during stacking context tree construction

Manage containing blocks and WebRender SpaceAndClip during stacking context tree construction using the ContainingBlockInfo data structure. This will allow us to reuse this data structure whenever we traverse the fragment tree. In addition, StackingContextBuilder is no longer necessary at all. This change also fixes some bugs where fixed position fragments were not placed in the correct spatial node. Unfortunately, these fixes are difficult to test because of #<!-- nolink -->29659.
