gh-102304: Move _Py_RefTotal to _PyRuntimeState (gh-102543) The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState. Folks that currently read _Py_RefTotal directly would have to start using _Py_GetGlobalRefTotal() instead. https://github.com/python/cpython/issues/102304

gh-102304: Move the Total Refcount to PyInterpreterState (gh-102545) Moving it valuable with a per-interpreter GIL. However, it is also useful without one, since it allows us to identify refleaks within a single interpreter or where references are escaping an interpreter. This becomes more important as we move the obmalloc state to PyInterpreterState. https://github.com/python/cpython/issues/102304

gh-107080: Fix Py_TRACE_REFS Crashes Under Isolated Subinterpreters (gh-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.
