Clean up the VDM default virtual display flags.

1. Remove FLAG_PUBLIC to support private virtual displays on virtual
   devices
2. Remove FLAG_ROTATES_WITH_CONTENT to support fixed orientation
   displays
3. Remove FLAG_OWN_CONTENT_ONLY to be consistent with the default
   behavior in the system (respect AUTO_MIRROR flags)
4. Remove DESTROY_CONTENT_ON_REMOVAL to support app continuity. Only
   add it by default when the VD policy is to not show the streamed
   apps in recents.
5. Add TOUCH_FEEDBACK_DISABLED by default. Even when some touch
   feedback is required on the client device, it is the one injecting
   the touch, so it doesn't need this signal from the host.
