Presubmit check will test will new changes be overriden by autoroll
or not. In more details presubmit will check:
1. Each dependency in third_party have to be specified in one of:
   a. THIRD_PARTY_CHROMIUM_DEPS.json
   b. THIRD_PARTY_WEBRTC_DEPS.json
2. Each dependency not specified in both files from #1
3. Changes won't be overriden by chromium third_party deps autoroll:
   a. Changes were made in WebRTC owned dependency
   b. Changes were addition of new Chromium owned dependency
