Update to Chromium revision b0aa1fb5 (#296183).

- Restore CefRenderHandler::OnScrollOffsetChanged.
- Add new RT_PING and RT_SERVICE_WORKER resource type values.
- The resource type for image sub-resource loads has changed from RT_IMAGE to RT_PREFETCH (this is a regression, see http://crbug.com/415253#c23).
- Add a patch to fix a crash in Scheduler::swapQueuesRunPendingTasks* (http://crbug.com/415478).
- Add documentation for cef_key_event_type_t values.
