I recently added some tests to test_imp, but @warsaw is removing that file in gh-98573. The tests are worth keeping so here I'm moving them to test_import.

This API was [removed in Python
3.12](python/cpython#98040).

Fixes Python 3.12 support in `grpcio` tests.

This is relevant to #33063.

See also #33492.

I have actually only tested this in a form backported to grpc 1.48.4,
and I am not able to test the change to `bazel/_gevent_test_main.py`
directly. However, the backported form allows me to build grpc 1.48.4
for Fedora Rawhide with Python 3.12, and I believe the version in this
PR to be correct—especially, if CI passes for Python 3.11, I believe
this part of the test code will continue to work in Python 3.12.
