The continue window is owned by the desktop environment now.

This CL completely removes HostUserInterface and It2MeHostUserInterface classes, making the desktop enviroment (It2MeDesktopEnvironment) responsible for creation of the UI. Platform-specific implementations of ContinueWindow have been rewritten on top of HostWindow class.

Collateral changes:
  - HostScriptObject creates a instance of base::ThreadTaskRunnerHandle so that timers could run on the plugin thread.
  - No more "uninteresting mock" messages caused by the continue and disconnect windows when running remoting_unittests.
