Recent changes to DecomposeMemoryAccess meant we lost the dependency information between the user of a module-scope variable of the storage / uniform address space and the variable.
Add dependency information to ast::InternalAttribute so this can be tracked.
This change also means that symbol renaming after the DecomposeMemoryAccess should work.
