Revert "Use correct range to highlight line continuation error" (#12089) 
This PR reverts https://github.com/astral-sh/ruff/pull/12016 with a
small change where the error location points to the continuation
character only. Earlier, it would also highlight the whitespace that
came before it.

The motivation for this change is to avoid panic in
https://github.com/astral-sh/ruff/pull/11950. For example:

```py
\)
```

Playground: https://play.ruff.rs/87711071-1b54-45a3-b45a-81a336a1ea61

The range of `Unknown` token and `Rpar` is the same. Once #11950 is
enabled, the indexer would panic. It won't panic in the stable version
because we stop at the first `Unknown` token.

Ruff Python Parser

Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.

Try out the parser in the playground.

Python version support

The parser supports the latest Python syntax, which is currently Python 3.12. It does not throw syntax errors if it encounters a syntax feature that is not supported by the target-version. This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
