Disable camera zoom control in video mode

instead of removing, and other fixes.

+ Add images for disabled state.
+ Remove zoom stub.
+ In ZoomPicker, increase transition period from pressed to long pressed state
  to 300ms. 200ms is too short for single press and showing images in pressed
  state.
+ In ZoomPicker, restore image to state list instead of normal-state image.

              this is circular dependency and is not allowed so it's very
              unfortunate that we have to hardcode the width here. -->
