Chris Bieneman	5dbb92d8cd	[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.

Chris Bieneman	66eabeb65d	[HLSL] Add RWBuffer default constructor ... This fills out the default constructor for RWBuffer to assign the handle with the result of __builtin_hlsl_create_handle which we can then treat as a pointer to the resource data through the mid-level of the compiler.

Chris Bieneman	fe13002bb3	[HLSL] Add __builtin_hlsl_create_handle ... This is pretty straightforward, it just adds a builtin to return a pointer to a resource handle. This maps to a dx intrinsic. The shape of this builtin and the underlying intrinsic will likely shift a bit as this implementation becomes more feature complete, but this is a good basis to get started. Depends on D128569.
