Remove less used parser dependencies (#11718) 
## Summary

This PR removes the following dependencies from the `ruff_python_parser`
crate:
* `anyhow` (moved to dev dependencies)
* `is-macro`
* `itertools`

The main motivation is that they aren't used much.

Additionally, it updates the return type of `parse_type_annotation` to
use a more specific `ParseError` instead of the generic `anyhow::Error`.

## Test Plan

`cargo insta test`

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).
