Use Vertex Depth Range when zRange Exceeds farZ

Browse Source 
When the inverted depth range is unsupported and zRange is greater than farZ then min_depth becomes a negative value and far_depth will then exceed a depth of 1.0 (which is outside the scope of most backends and greater than GX_MAX_DEPTH of the console).

This happens when the backend supports depth clamping the min_depth is not clamped to zero.
