* This allows better identification of a shader from its reflection
bundle. The entry point was already 'optionally' in the debug info
struct which is no longer a great location for it.
* For APIs where the entry point isn't contractual and it might not be
listed, instead we just fall back to 'main'. This means that the UI
or anyone fetching the info can be guaranteed that some sensible entry
point will be listed.
* Also for the debug info, remove the 'entryFile' index and instead just
guarantee that as much as possible the entry point will be in the
first file in the list.
* Things like addressing modes, stencil operations, and other things the
UI didn't need to know about previously were only exposed as string
values to be passed through and displayed.
* Now we describe these with enums so the API can be properly
introspected and used by consumers that might want to know the actual
values of these states.
* Since the Vulkan views are tighter and more strictly specified, we can
always safely use the view format (in the non-mutable case it must
exactly match the underlying resource's format).
* For now, we just assume that cbuffers are tightly packed according to
D3D11 rules (matrices, structs, float3/4 are all float4 aligned), and
once final SPIR-V is generated everything should have explicit
offsets, strides, and sizes
