[PATCH] Remove HIR MacroItem and other hir macro forward declarations

[Mark Wielaard <mark@klomp.org>]

Almost all HIR Macro related trees were already removed by
https://github.com/Rust-GCC/gccrs/pull/492

But there was still one MacroItem class left in rust-hir.h and several
(unused) forward declarations in various other hir .h files. Remove
them all.

Resolves: https://github.com/Rust-GCC/gccrs/issues/69
