[M108 Migration] Bringup Link Effect feature

Link effect feature produces sound effect when user taps
on elements. The functionality is enabled on few elements
that satisfy certain contraints. This check is done at
blink side on GestureTap event and notifies
RenderFrameObserver to play the sound effect using tizen
haptic feedback library on mobile.
