Update type annotation parsing API to return Parsed (#11739) 
## Summary

This PR updates the return type of `parse_type_annotation` from `Expr`
to `Parsed<ModExpression>`. This is to allow accessing the tokens for
the parsed sub-expression in the follow-up PR.

## Test Plan

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).
