Fix a handful of type annotations. (#10446)

* switch from `types.CoroutineType` to `typing.Coroutine`

these should be identical semantically, and since `defer.ensureDeferred` is
defined to take a `typing.Coroutine`, will keep mypy happy

* Fix some annotations on inlineCallbacks functions

* changelog
