Parallel Shader Compilation for Ray Tracing Pipeline States

In ray tracing, a single pipeline state object (PSO) can contain any number of shaders. This number can grow large, depending on scene content and ray types handled with the PSO; construction cost of the state object can significantly increase. The DXR API makes it possible to distribute part of the creation work to multiple threads by utilizing collections. A collection is a ID3D12StateObject with type D3D12_STATE_OBJECT_TYPE_COLLECTION.
