gh-106084: Remove old PyObject call aliases (#106085)

Remove old aliases which were kept backwards compatibility with
Python 3.8:

* _PyObject_CallMethodNoArgs()
* _PyObject_CallMethodOneArg()
* _PyObject_CallOneArg()
* _PyObject_FastCallDict()
* _PyObject_Vectorcall()
* _PyObject_VectorcallMethod()
* _PyVectorcall_Function()

Update code which used these aliases to use new names.
