Allow unrestricted depth bounds

SwiftShader exposes VK_EXT_depth_range_unrestricted which allows depth values outside [0, 1]. depthBoundsTest code asserted on values outside that range and were causing test failures. Bug: b/181655689 Tests: dEQP-VK.pipeline.depth_range_unrestricted.* Change-Id: Iae9103b802672960f2f0f67710f75165780f1368 Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/54110Reviewed-by: Nicolas Capens <nicolascapens@google.com> Commit-Queue: Sean Risser <srisser@google.com> Tested-by: Sean Risser <srisser@google.com>
