Move maximize/fullscreen/restore to shell

 With this CL, window is now correctly maximized/fullscreen'ed on aura desktop.

* Added OnPropertyChanged to WindowObserver
* Added Get/Set IntProperty to simplify handling int value properties.
* Remove IsOrContainsFullscreen. Added Workspace::ContainsFullscreen instead. We need this to autohide launcher.

BUG=97257,97259
TEST=new test for property change notification. existing tests are updated, except maximized/fullscreen drag test. I'll add it to new set of tests that verifies window dragging within workspace.
