[syntax-errors] `yield`, `yield from`, and `await` outside functions (#17298) 
Summary
--

This PR reimplements [yield-outside-function
(F704)](https://docs.astral.sh/ruff/rules/yield-outside-function/) as a
semantic syntax error. Despite the name, this rule covers `yield from`
and `await` in addition to `yield`.

Test Plan
--

New linter tests, along with the existing F704 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).
