[3.14] gh-142095: Use thread local frame info in `py-bt` and `py-bt-full` when available (gh-143371) (#143566)

In optimized and `-Og` builds, arguments and local variables are frequently
unavailable in gdb. This makes `py-bt` fail to print anything useful. Use the
`PyThreadState*` pointers `_Py_tss_gilstate` and `Py_tss_tstate` to find the
interpreter frame if we can't get the frame from the
`_PyEval_EvalFrameDefault` call.
(cherry picked from commit 49c3b0a67a77bb42e736cea7dcbc1aa8fa704074)
