[syntax-errors] Check annotations in annotated assignments (#17283) 
Summary
--

This PR extends the checks in #17101 and #17282 to annotated assignments
after Python 3.13.

Currently stacked on #17282 to include `await`.

Test Plan
--

New inline tests. These are simpler than the other cases because there's
no place to put generics.

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).
