optimize usage of observers in MDV and PolymerExpressions #12392
Description
We often create observers even for silly things, e.g. observing the "value" property of a CompoundBindings. FancySyntax has even more observers. We can skip at least the PathObserver if the thing we're observing just has a ".value"

this is partially fixed. NodeBinding is smart about not creating yet-another-pathobserer. TemplateIterator is smarter too.
Still work to be done:
Removed Library-MDV label.

Rafael has been slowly fixing this on the observe-js/TemplateBinding/polymer-expressions side of the world, and we've been porting those changes. I'd say it's good enough at this point.
Added Fixed label.
