Add remoteTransition for moveTaskToFront(), and apply minimize reparent

Support new alt-tab animation behaviour:
1. allow passing a RemoteTransition through showDesktopApp(), and
2. reparent the leash of the minimize-change before applying that
RemoteTransition so the minimize window doesn't move in front of other
windows.

Test: manual, and DesktopWindowLimitRemoteHandlerTest
