  1. Vulkan: Clip clamped depth in geometry shader. 

    This corrects deformed geometry on Mali devices which don't support
user-space clipping but do support depth clamp.

  3. Vulkan: Correct clamped Z clip when clipping neg Z. 

    In the geometry shader, if used, we need to output the clip distance from
the clamped Z clip or it gets lost.

  4. GPU: Optimize clip distances needed. 

    We only need to write one clip distance to clip clamped depth, since we
don't clamp when it needs clipping on both sides.
