Rollup merge of #72724 - Aaron1011:revert-tokenstream-expand, r=petrochenkov
Revert recursive `TokenKind::Interpolated` expansion for now The crater run https://github.com/rust-lang/rust/issues/72622 revealed many root regressions, at least one of which is going to take some time to fix. For now, let's revert https://github.com/rust-lang/rust/pull/72388 to allow the 709 affected crates to continue building on the latest nightly.
