Prep for moving files into components/invalidation

Prep for moving files into components/invalidation

Refactors some dependencies to prepare for an upcoming move of
invalidator code from sync/internal_api/public/base to
components/invalidation.

Highlights include:
- Remove some sync/ dependencies on invalidator_state.h
- Refactor P2PInvalidator to not require model_type.h
- Remove ModelType dependencies from invalidator_util.h.  Introduce
  sync/tools/invalidation_helper.h and
  chrome/browser/sync/glue/invalidation_helper.h to replace it.

The next patch will be ugly, so I decided to put as much of it as I could into a
separate CL.  Here it is.

Pavel: please review.
Nicolas: we'll need your LGTM because of the added dependency on
cacheinvalidation from sync/tools.

I'm not sure why, but somehow the presubmit scripts don't think that zea@ is an
OWNER of google/cacheinvalidation.  Apparently ben@ is an owner, though. 
TBR'ing him.
