Adds window properties for
 * kEscHoldToExitFullscreen - if true holding esc for 2s will exit
   fullscreen.
 * kEscHoldExitFullscreenToMinimized - if true window is minimized
   when it exits from fullscreen rather than being restored to normal.

AppServiceAppWindowLauncherController sets these properties on:
 * Borealis to use esc, and minimize on exit
 * PluginVM to use esc, and restore on exit
