gccrs: expand: Add stub function for attribute expansion
Add a stub function and utility functions that should be called on some nodes to expand attribute procedural macros. gcc/rust/ChangeLog: * expand/rust-expand-visitor.cc (ExpandVisitor::expand_outer_attribute): Stub for a single attribute expansion. (ExpandVisitor::visit_outer_attrs): Visit the attributes to expand on a given item. * expand/rust-expand-visitor.h: Add function prototypes.
