bpo-37414: Remove sys.callstats() (GH-14398)

Remove the undocumented sys.callstats() function. Since Python 3.7,
it was deprecated and always returned None. It required a special
build option CALL_PROFILE which was already removed in Python 3.7.

-Return a tuple of function call statistics.
-
-A tuple is returned only if CALL_PROFILE was defined when Python was
-built.  Otherwise, this returns None.
-
-When enabled, this function returns detailed, implementation-specific
-details about the number of function calls executed. The return value
-is a 11-tuple where the entries in the tuple are counts of:
-0. all function calls
-1. calls to PyFunction_Type objects
-2. PyFunction calls that do not create an argument tuple
-3. PyFunction calls that do not create an argument tuple
-   and bypass PyEval_EvalCodeEx()
-4. PyMethod calls
-5. PyMethod calls on bound methods
-6. PyType calls
-7. PyCFunction calls
-8. generator calls
-9. All other calls
-10. Number of stack pops performed by call_function()
