typeInjections for Ember.View

This change makes it possible for Ember.View's instantiated in templates
and other Ember core code to run type injections through the container,
even if they're anonymous `Ember.View.extend` classes. This works by
performing a reverse lookup on the container on all parent classes of
the view and running any typeInjections that match registered parent
classes. But the algorithm is generalized to all class types, and not
just Views, though it seems that this problem of type injections not
running is unique to Views and the way they were being directly
`.create()`d by Ember core code.
