Implement VK_EXT_depth_clip_enable

Normally the vertex processor will clip geometry that's outside of the near and far planes. However, when depthClamp is enabled, depth clipping must be disabled. So this change also enables the extension that allows users to explicitly control depth clipping. Bug: b/185814882 Tests: dEQP-VK.clipping.clip_volume.depth_clip.* Change-Id: Iaab31c17cac382cf55a8c50d8e7e7d4c87b55272 Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/53968 Presubmit-Ready: Alexis Hétu <sugoi@google.com> Reviewed-by: 's avatarNicolas Capens <nicolascapens@google.com> Commit-Queue: Sean Risser <srisser@google.com> Tested-by: 's avatarSean Risser <srisser@google.com>
