r300: reorder fog coordinate and WPOS fp attributes
HW TCL path currently assumed fog, WPOS order. The order was inverted for SW TCL path.
This hopefully fixes rest of fog and WPOS related bugs.
Additionally fix some indentation, don't route unnecessary components of fog coordinates for performance reasons and simplify vertex
attribute emitting for SW TCL path.
