workspacesView: Derive workspace mode from overview state

Browse Source 
WorkspacesView uses the floating layout when the overview is in window
picker mode, and the session layout when the overview is in app grid
mode. Up until now, the fit mode adjustment was used to derive the
workspace mode, but it is incomplete as it doesn't have the full range
of workspace states.

Make ViewSelector cascade the overview adjustment to WorkspacesDisplay,
and use the overview adjustment itself to derive the workspace mode.

Extra workspaces don't have to account for the fit mode, and thus are
basically a clamp(state, 0, 1) of the overview state. However, don't
call animateTo/FromOverview() anymore, since they ease the workspace
mode adjustment.
