Add always on top feature support

Add basic functionalities for always on top feature.

- Add a new flag to WindowConfiguration to represent a task wanting to
be on top.
- Update the logic on changing the z-order of windows to make sure
always on top windows are placed above other windows.

      set, the app is above the other Android apps and Chrome windows.
