Rollup merge of #107813 - compiler-errors:bad-impl-trait-in-macro-is-ok, r=estebank

Do not eagerly recover for bad `impl Trait` types in macros

Fixes #107796

cc #106712, ```@estebank``` and ```@Ezrashaw``` please make sure to use [`Parser::may_recover`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_parse/parser/struct.Parser.html#method.may_recover) for all eager-token-consuming parser recoveries.

This also fixes a separate regression from #99915, that was introduced before we added `may_recover` though.
