Separating various UI properties into state variables

Browse Source 
> Using workspace scale and translation for all-apps
> Without quickstep, workspace has the parallex effect as before
> With quickstep, workspace scales down to match the recents card width
> Using a single animator for recents views in case of state transtion and
  controlled transition to prevent going into inconsistant state.
