gh-107630: Fix Remaining Subinterpreters Crashes on Py_TRACE_REFS Builds (gh-107750)

This is a follow-up to gh-107567 and gh-107733.

We skip test_basic_multiple_interpreters_deleted_no_reset on tracerefs builds.  The test breaks interpreter isolation a little, which doesn't work well with Py_TRACE_REFS builds, so I feel fine about skipping the test.
