[3.12] gh-107471: Fix Refleaks in test_import (gh-107569) (#107571)
gh-107471: Fix Refleaks in test_import (gh-107569)
gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module.
The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests.
(This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)
(cherry picked from commit 017f047183fa33743f7e36c5c360f5c670032be3)
