[3.8] bpo-42630: Improve error reporting in Tkinter for absent default root (GH-23781) (GH-23854)
* Tkinter functions and constructors which need a default root window raise now RuntimeError with descriptive message instead of obscure AttributeError or NameError if it is not created yet or cannot be created automatically. * Add tests for all functions which use default root window. * Fix import in the pynche script. (cherry picked from commit 3d569fd6dccf9f582bafaca04d3535094cae393e)
