Issue #23571: _Py_CheckFunctionResult() now gives the name of the function

which returned an invalid result (result+error or no result without error) in
the exception message.

Add also unit test to check that the exception contains the name of the
function.

Special case: the final _PyEval_EvalFrameEx() check doesn't mention the
function since it didn't execute a single function but a whole frame.
