tests: remove more old async tests

The rejection of #6025 indicates that if stackless coroutines return to Zig, they will look quite different; see #23446 for the working draft proposal for their return (though it will definitely be tweaked before being accepted). Some of this test coverage was deleted in 40d11cc, but because stackless coroutines will take on a new form if re-introduced, I anticipate that essentially *none* of this coverage will be relevant. Of course, if it for some reason is, we can always grab it from the Git history.
