gccrs: Add proc macro ast representation
When resolving proc macros it is convenient to store every macro
directly in the extern crate. These class in the ast module provide a
better abstraction over the raw ProcMacro::{CustomDerive, Bang,
Attribute} structures provided by the proc_macro library.
gcc/rust/ChangeLog:
* ast/rust-ast.h (class BangProcMacro): Add new proc macro
abstraction.
(class AttributeProcMacro): Likewise.
(class CustomDeriveProcMacro): Likewise.
