pythongh-106084: Remove _PyObject_CallMethod() function
Remove the following functions from the public C API: * _Py_CheckFunctionResult() * _PyObject_CallMethod() * _PyObject_CallMethodId() * _PyObject_CallMethodIdNoArgs() * _PyObject_CallMethodIdObjArgs() * _PyObject_CallMethodIdOneArg() * _PyObject_MakeTpCall() * _PyObject_VectorcallMethodId() * _PyStack_AsDict() Move these functions to the internal C API (pycore_call.h). No longer export the following functions: * _PyObject_Call() * _PyObject_CallMethod() * _PyObject_CallMethodId() * _PyObject_CallMethodIdObjArgs() * _PyObject_Call_Prepend() * _PyObject_FastCallDictTstate() * _PyStack_AsDict() The following functions are still exported for stdlib shared extensions: * _Py_CheckFunctionResult() * _PyObject_MakeTpCall()
