Add client based Geolocation provider

Reviewed by Dan Bernstein.

Add first cut of a client based Geolocation provider. This is guarded by
ENABLE(CLIENT_BASED_GEOLOCATION) and is off by default for now. This adds a
GeolocationControllerClient interface that no-one currently implements,
but will in a subsequent patch.
