Fixes the Mac build

- JavaInstanceJSC.cpp - Adds ANDROID guards around some temporary logging
- Geolocation.cpp - Adds ANDROID guards around changes waiting to be upstreamed
- WebChromeClient.h / EmptyClients.h - Pulls the Mac part of a WebKit change for which only the Android part was cherry-picked in https://android-git.corp.google.com/g/#change,41747
