Add expr_2021 nonterminal and feature flag
This commit adds a new nonterminal `expr_2021` in macro patterns, and `expr_fragment_specifier_2024` feature flag. For now, `expr` and `expr_2021` are treated the same, but in future PRs we will update `expr` to match to new grammar. Co-authored-by: Vincezo Palazzo <vincenzopalazzodev@gmail.com>
