Add PyPy3.11 (PyO3#4760)

* allow pypy3.11

* run CI on pypy3.11

* change const declaration

* change link name for PyExc_BaseExceptionGroup

* PyObject_DelAttr* are inline functions on pypy3.11

* use nightly until official release

* DOC: add a news fragment

* conditionally compile 'use' statements

* fix format

* changes from review

* pypy 3.11 released

* fixes for PyPy

* typo

* exclude _PyInterpreterFrame on PyPy

* more pypy fixes

* more excluding _PyFrameEvalFunction on PyPy

* fixes for PyPy struct differences

* format

* fix test
