Use CommentRanges in backwards lexing (#7360)
## Summary

The tokenizer was split into a forward and a backwards tokenizer. The
backwards tokenizer uses the same names as the forwards ones (e.g.
`next_token`). The backwards tokenizer gets the comment ranges that we
already built to skip comments.

Add support for multi-character operator tokens to SimpleTokenizer (#6563)
## Summary

Allows for proper lexing of tokens like `->`.

The main challenge is to ensure that our forward and backwards
representations are the same for cases like `===`. Specifically, we want
that to lex as `==` followed by `=` regardless of whether it's a
forwards or backwards lex. To do so, we identify the range of the
sequential characters (the full span of `===`), lex it forwards, then
return the last token.

## Test Plan

`cargo test`

Rename ruff_python_whitespace to ruff_python_trivia (#5886)
## Summary

This crate now contains utilities for dealing with trivia more broadly:
whitespace, newlines, "simple" trivia lexing, etc. So renaming it to
reflect its increased responsibilities.

To avoid conflicts, I've also renamed `Token` and `TokenKind` to
`SimpleToken` and `SimpleTokenKind`.
