Title: ENH: Added size_state trait to Window for maximized information.

Window now has `size_state` trait which is synced to the window's
maximized state and also stored in the task's persistent layout.

Also added a default _create_control() method to Window (which is close
to the implementation of ApplicationWindow's _create_control) to make it
easier to create window without needing an application and which can
set the window's size_state correctly.
