For each resource or resource array member of a struct declared at global scope or inside a `cbuffer`, create an implicit global variable of the same resource type. The variable name will be derived from the struct instance name and the member name and will be associated with the struct declaration using a new attribute `HLSLAssociatedResourceDeclAttr`.
