Refactor Instant to separate out preview control

Separates out Show/Hide logic into a separate |InstantPreviewController|
class.  This class follows an observer pattern, observing the |InstantModel|
changes.  The model is held by the |InstantController|.

The goal with this is to pave the way for future changes that will expand the
complexity of the "view" logic, especially in the area of coordinating the
animations used with --enable-instant-extended-api features.

BUG=142785
TEST=No functional change.  Refactoring only.
