HLSL: struct splitting: assignments of hierarchical split types

This commit adds support for copying nested hierarchical types of split types. E.g, a struct of a struct containing both user and builtin interstage IO variables. When copying split types, if any subtree does NOT contain builtin interstage IO, we can copy the whole subtree with one assignment, which saves a bunch of AST verbosity for memberwise copies of that subtree.
