Remove dependency on ruff_rowan (#2875)

This PR removes the dependency on `ruff_rowan` (i.e., Rome's fork of rust-analyzer's `rowan`), and in turn, trims out a lot of code in `ruff_formatter` that isn't necessary (or isn't _yet_ necessary) to power the autoformatter.

We may end up pulling some of this back in -- TBD. For example, the autoformatter has its own comment representation right now, but we may eventually want to use the `comments.rs` data structures defined in `rome_formatter`.
