Switch to client-based Geolocation

The motivation for this switch is that it is required to enable
PREEMPT_GEOLOCATION_PERMISSION. See b/4500947.

The switch involves changing lots of Android's WebKit plumbing to use a new
GeolocationClientAndroid in WebKit (called from
WebCore::GeolocationController), rather than the existing
GeolocationServiceAndroid in WebCore/platform (called from
WebCore::Geolocation). This is complicated by the need to support mocking for
LayoutTests.

The pattern used is very similar to that used for DeviceOrientation and
DeviceMotion. This patch ...
- Enables CLIENT_BASED_GEOLOCATION
- Leaves PREEMPT_GEOLOCATION_PERMISSION disabled for now
- Removes GeolocationServiceAndroid
- Adds a new GeolocationClientAndroid
  - Just a proxy to real client
- Adds a new GeolocationManager
  - Manages switching between the real and mock clients
  - Provides the appropriate client to GeolocationClientAndroid
  - Plumbs to the real client calls for permissions and for suspending/resuming
- Adds a new GeolocationClientImpl
  - The real client
  - Based heavily on GeolocationServiceAndroid
  - Delegates to GeolocationServiceBridge, as GeolocationServiceAndroid did
  - Calls back directly to GeolocationController
  - Owns the existing GeolocationPermissions
- Updates WebViewCore to call the GeolocationManager for permissions and for
  suspending/resuming
- Removes superfluous ChromeClient methods for permissions

Note that support for mocking will be added in a later change. See bug for
details.
