Merge #6893

6893: Move to upstream `macro_rules!` model r=matklad a=jonas-schievink

This changes `macro_rules!` from being treated as a macro invocation to being a first-class item. It also disallows using an additional ident argument for regular macros, so `m! ident(...);` now fails to parse.

This matches upstream Rust, and makes the code somewhat simpler by removing repeated "is this a `macro_rules!` call" checks. It will also simplify allowing visibilities on macros, which is currently being proposed in https://github.com/rust-lang/rust/pull/78166.
