gh-96021: Explicitly close the IsolatedAsyncioTestCase runner in tests #96135

Tests for IsolatedAsyncioTestCase.debug() rely on the runner be closed
in __del__. It makes tests depending on the GC an unreliable on other
implementations. It is better to close the runner explicitly even if
currently there is no a public API for this.

It does not fix gh-96021, it only uses a workaround until we find better solution (which perhaps could not be backported).
