bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)

* Move _PyObject_CallNoArgs() to pycore_call.h (internal C API).
* _ssl, _sqlite and _testcapi extensions now call the public
  PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs().
* _lsprof extension is now built with Py_BUILD_CORE_MODULE macro
  defined to get access to internal _PyObject_CallNoArgs().
