gh-153513: Remove obsolete Tk version guards in tkinter tests (GH-153615)

Since gh-153513, _tkinter returns int, float and pixel objects for the
corresponding Tcl object types on all Tk versions.  The tests for the
Text "tabs" and ttk "padding" options therefore no longer need to expect
string tuples on Tk older than 8.6.14.
