[HLSL] Add Resource "shape" and "ROV" to HLSLResourceAttr

[llvm-beanz]

The HLSL Resource attribute currently captures the some of the possible types of resource information, but not all. The attribute should also capture the "Shape" of all resources, and have an optional bool for ROVs.

shape is done.
Need to ROV next.

We'll also need "HasCounter" here. We should check if anything else needs this treatment, but I think things like counts, element type, and stride should already be visible elsewhere in the AST.

See #74896

This is done as of #74896
