refactor(transformer/arrow-functions): do not inline non-trivial visitor method (#8321)

Follow-on after #8024. Don't inline `visit_statements` visitor method. This visitor is not so small, and always executes unconditionally. The compiler can decide whether to inline it or not. Where `#[inline]` is really valuable is:

1. Where the function is tiny so the cost of moving it into the caller is small. and
2. The function gets called a lot e.g. `visit_expression`, `visit_statement`, `visit_identifier_reference`.
3. Most commonly the function checks something and exits "nothing to do here". e.g. `visit_expression` where you only need to transform a particular type of `Expression`.
