Organize multi-window enabling

Browse Source 
Use AMS#mSupportsMultiWindow to indicate if some form of multi-window is
supported.
- If no multi-window implementation is enabled, this will be always set
to false.
- If a corresponding config is set to false, it will disable all forms
of multi-window.
