Auto merge of #53778 - petrochenkov:shadrelax2, r=nikomatsakis
resolve: Relax shadowing restrictions on macro-expanded macros Previously any macro-expanded macros weren't allowed to shadow macros from outer scopes. Now only "more macro-expanded" macros cannot shadow "less macro-expanded" macros. See comments to `fn may_appear_after` and added tests for more details and examples. The functional changes are a21f6f588fc28c97533130ae44a6957b579ab58c and 46dd365ce9ca0a6b8653849b80267763c542842a, other commits are refactorings.
