Rollup merge of #39419 - jseyfried:simplify_tokentree, r=nrc
Simplify `TokenTree` and fix `macro_rules!` bugs This PR - fixes #39390, fixes #39403, and fixes #39404 (each is a [breaking-change], see issues for examples), - fixes #39889, - simplifies and optimizes macro invocation parsing, - cleans up `ext::tt::transcribe`, - removes `tokenstream::TokenTree::Sequence` and `Token::MatchNt`, - instead, adds a new type `ext::tt::quoted::TokenTree` for use by `macro_rules!` (`ext::tt`) - removes `parser.quote_depth` and `parser.parsing_token_tree`, and - removes `quote_matcher!`. - Instead, use `quote_tokens!` and `ext::tt::quoted::parse` the result with `expect_matchers=true`. - I found no outside uses of `quote_matcher!` when searching Rust code on Github. r? @nrc
