upgrade_pythoncapi.py: disable "coding style" operations

[vstinner]

By default, upgrade_pythoncapi.py enables all operations. Some operations are not strictly required to support Python 3.10 and Python 3.11 and can introduce many "unwanted" changes:

• PyMem_MALLOC, PyObject_MALLOC, PyObject_NEW
• PyFrame_GetBack, PyFrame_GetCode
• PyThreadState_GetInterpreter, PyThreadState_GetFrame
• Py_TYPE, Py_SIZE, Py_REFCNT

Maybe keeping them by default is fine, there should be an easy way to only apply required changes. For example, Python 3.10 requires Py_SET_REFCNT and Python 3.11 requires Py_SET_SIZE.

Sounds good. Do you have a list of required changes, or do we need to assemble one?

I lost track of the issue, I prefer to close it for now.
