[HLSL] CodeGen HLSL Resource annotations

HLSL Resource types need special annotations that the backend will use
to build out metadata and resource annotations that are required by
DirectX and Vulkan drivers in order to provide correct data bindings
for shader exeuction.

This patch adds some of the required data for unordered-access-views
(UAV) resource binding into the module flags. This data will evolve
over time to cover all the required use cases, but this should get
things started.

Depends on D130018.
