ui/dbus: use shared memory when possible on win32
When the display surface has an associated HANDLE, we can duplicate it
to the client process and let it map the memory to avoid expensive copies.
Introduce two new win32-specific methods ScanoutMap and UpdateMap. The
first is used to inform the listener about the a shared map
availability, and the second for display updates.
