Description
The eventual goal here is to cache PSOs in a format that they can be reused; e.g. if the user creates two PSOs that only differ with depth-test, we could reuse the same PSO, and use dynamic state to flip things around. Even on D3D12, we could keep the same HLSL/DXC binary cached and only create a new PSO.
This is a very early version of this that still creates a new PSO, but switches to using dynamic state in Vulkan when available.
