gh-78335: Complete the widget option lists in tkinter docstrings (GH-152485)

Several widget __init__ docstrings omitted valid options, and Menubutton and
Message had no option list at all.  List every option supported by the widget,
tagging those added in Tk 9.0 and 9.1.

Add test_options_in_docstring, asserting that every option in OPTIONS is named
in the widget's __init__ docstring.  Options reported by keys() but not in the
docstring are only printed in verbose mode, as some depend on the Tk version.
