Move HideComplicationTouchHandler out of DreamTouchModule.

HideComplicationTouchHandler provides visibility control over
complications on the dream overlay. As complications move out
of the overlay, the related dependences such as
HideComplicationTouchHandler must also relocate. This changelist
refactors the touch handler into a new package and related
component. Also, the handler is now provided at the top level
DreamOverlayModule rather than the DreamTouchModule.

Note that some naming is temporary, due to collisions as packages
are transferred out from under the dream package. For example,
the dreamcomplication package will eventually become the
complication package.
