Subject: Shader Execution Reordering for VK (#2491)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Fixes around MakeMiss.

* Add preliminary support for HitObject::MakeHit.

* Make Nop.

* Add HitObject::TraceRay.

* HitObject::Invoke for VK.

* Remove line numbers from SER GLSL output.

* Add support for HitObjectAttributes
Add support for GLSL HitObject.GetAttributes<T>()
Simplified code around getting locations.

* Be more explicit about requiring GL_EXT_ray_tracing in SER.

* Split out LocationTracker from CLikeEmitter.

* Small doc improvements.

* Add motion ray support.

* Use inlining to get correct GLSL behavior around hitObjectNV.

* Add assignment HitObject test.

* Add a HitObject array test. Shows doesn't work correctly for VK/GLSL.

* Add call to `hitObjectGetAttributesNV` before getting attributes.
