Fix syntax error false positives for `await` outside functions (#21763) 
## Summary

Fixes #21750 and a related bug in `PLE1142`. We were not properly
considering generators to be valid `await` contexts, which caused the
`F704` issue. One of the tests I added for this also uncovered an issue
in `PLE1142` for comprehensions nested within async generators because
we were only checking the current scope rather than traversing the
nested context.

## Test Plan

Both of these rules are implemented as semantic syntax errors, so I
added tests (and fixes) in both Ruff and ty.
