Add support for VK_EXT_depth_clip_control. (#5027)

Browse Source 
* Add support for VK_EXT_depth_clip_control.

* Code review feedback

Minor formatting

Co-authored-by: gdkchan <gab.dark.100@gmail.com>

* Check .DepthClipControl to make sure the host actually supports the feature.

* Review feedback: remove Vulkan platform switch, relying on QueryHostSupportsDepthClipControl to drive the behaviour - OpenGL returns true, and any future platforms that don't support the [-1, 1] depth mode can return false for the transformation.
