chris kulla b00b7d70d0 Organize Ray Tracing shaders by their payload ...

Every shader now has the ability to declare which payload it uses. HitGroup, Miss and Callable shaders may only specify a single type, whereas Raygen shaders may provide more than one.

The global raytracing shader libraries have been categorized according to their payload type, which helps facilitate the creation of minimal ray-tracing pipelines.

Avoid adding callable shaders to the RTPSO if they are not being used.

All RHI shader compilers and shader loaders that support ray tracing have been modified to track an extra uint representing the payload type flagged in the source (at time of compilation).

Add the RayTracingPayloadType to the shadermap DDC key so that we can properly detect when a shader's payload type is invalidated. This is required because we serialize the payload type into the shaders from the C++ side.
