…ters (pythongh-107567)

The linked list of objects was a global variable, which broke isolation between interpreters, causing crashes. To solve this, we've moved the linked list to each interpreter.

…lated Subinterpreters (pythongh-107567) (python#107599)".

This reverts commit 6e4eec7 (pythongh-107648).

This finishes fixing the crashes in Py_TRACE_REFS builds.  We missed this part in gh-107567.

…lds (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.
