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.
