Description: This reworks tkinter.simpledialog to match the look and feel of the native Tk dialogs: SimpleDialog is a port of ::tk_dialog, and Dialog is a base class whose button box is modelled on ::tk::MessageBox. SimpleDialog, askinteger, askfloat and askstring now use the themed tkinter.ttk widgets by default; the Dialog base class still defaults to the classic widgets for compatibility. Both classes gained a keyword-only use_ttk parameter to select the widget set. Both dialogs follow the message-box keyboard conventions: button accelerators (Alt + the underlined letter), a default ring that follows the keyboard focus, and that invokes the focused button. SimpleDialog gained bitmap and detail parameters, draws the standard icons with themed images in the ttk version, and accepts mappings of button options as buttons entries. The message and detail font and wrap length are taken from the Tk option database and can be overridden by the application. The new helpers _temp_grab_focus, _underline_ampersand and _find_alt_key_target can be reused by other tkinter dialogs, as _setup_dialog already is. Several bugs found by comparison with the Tcl sources were fixed. Issue: gh-59396
