Add declarations and helpers for Google Search counting.

We want to count the number of searches from various access points in Chrome. To do this, we've added a new UMA enumerated histogram to track these values (GoogleSearch.AccessPoint). These are the necessary declarations for various search access points that will be added shortly.

We've also added a IsGoogleSearchUrl helper to google_util to identify search URLs.

BUG=
TEST=Ensure that unit tests GoogleUtilTest all succeed.
