[DirectX] Implement shader flag analysis for EnableRawAndStructuredBuffers

[bogner]

If Raw or Structured buffers are used, the EnableRawAndStructuredBuffers shader flag must be set. We can implement this by looking at the resource kind of the return type of llvm.dx.resource.handlefrom intrinsics.

@bharadwajy - is there an existing issue tracking this?

No. It appears that I missed filing one earlier.

No. It appears that I missed filing one earlier.

@bharadwajy - is this a one off, or is this one of a class of flags that got missed?

It is a one off and has been added to the class of flags based on resource properties as part of creation of this issue by @bogner. I've also added this to the issue that tracks implementation of flags needed for DML Shader compilation.

Ok - Justin seemed to suggest it was needed for particle_life?
