ffef71d1 - [syntax-errors] `yield`, `yield from`, and `await` outside functions (#17298)

[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. --------- Co-authored-by: Dhruv Manilawala <dhruvmanila@gmail.com>
