environment: Add convenience method for adjustment transitions

By now, Tweener is used exclusively to animate changes to the
StAdjustment:value property. But not for long, as now that we
implement the same transition API as Clutter.Actor, we can
re-use the existing convenience method for property transitions
for adjustment changes as well.
