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 -- Simple, new inline tests, along with the existing F704 test. A huge number of existing parser tests also had to be updated. These are all in the second commit. For `test_err` cases, I mostly just accepted the new semantic errors alongside the existing syntax errors. For `test_ok` cases, I either deleted the lines with new errors, or nested the offending lines in a function. I think I only deleted lines from the first two inline tests I updated, and all of the other fixtures should be nested. The `await` cases should actually be nested inside of `async` functions, but I've intentionally left them as synchronous functions for now because I'm planning to implement that check next.
Summary -- This PR reimplements [return-outside-function (F706)](https://docs.astral.sh/ruff/rules/return-outside-function/) as a semantic syntax error. These changes are very similar to those in #17298, which this is currently stacked on. Test Plan -- Simple new inline tests, as well as updates to existing tests in the second commit.

There was a problem hiding this comment.
nit: I think the function names don't matter here so would prefer to just keep it _

Could I get one more quick review here? Like in #17298, I reverted the parser snapshot changes and moved everything to a linter test. It's much, much smaller now. The function scope tracking is now on the |
