Disable window and transition animations on computercontrol displays

Introduce a method in WindowManagerInternal to enable/disable window
and transiton animations for a display, and store a boolean in
DisplayContent to indicate on/off state of animations. VDM service
calls this method for every display created for computercontrol (this
will also be called when a ComputerControlSession is attached/detached
to a MirrorView to re-enable animations). WMCore notifies WMShell using
a new method in IDisplayWindowListener about animations turned on/off
for a display, to play transitions accordingly.
