Rollup merge of #144579 - joshtriplett:mbe-attr, r=petrochenkov
Implement declarative (`macro_rules!`) attribute macros (RFC 3697) This implements [RFC 3697](https://github.com/rust-lang/rust/issues/143547), "Declarative (`macro_rules!`) attribute macros". I would suggest reading this commit-by-commit. This first introduces the feature gate, then adds parsing for attribute rules (doing nothing with them), then adds the ability to look up and apply `macro_rules!` attributes by path, then adds support for local attributes, then adds a test, and finally makes various improvements to errors.
