Adds support for accessing individual resources from fixed-size global resource arrays. Design proposal: https://github.com/llvm/wg-hlsl/blob/main/proposals/0028-resource-arrays.md Enables indexing into globally scoped, fixed-size resource arrays to retrieve individual resources. The initialization logic is primarily handled during codegen. When a global resource array is indexed, the codegen translates the `ArraySubscriptExpr` AST node into a constructor call for the corresponding resource record type and binding. To support this behavior, Sema needs to ensure that: - The constructor for the specific resource type is instantiated. - An implicit binding attribute is added to resource arrays that lack explicit bindings (#152452). Closes #145424
