Uniform, extensible syntax for [$w identify] methods:

[$w identify $component $x $y].
All ttk::* widgets support [$w identify element $x $y];
widgets with other identifiable parts may have additional subcommands.
Notebook widgets support [$nb identify tab],
Panedwindow widgets support [$w identify sash].
Older 2-argument form [$w identify $x $y] still supported,
though it does different things depending on the widget.
