In order to get rid of the Chromium checkout for WebRTC, the plan is to instead of cloning all of Chromium, only clone the build, third_party and tools sub-directories. In order to do so, we must first move all things checked into the WebRTC tools/ directory somewhere else. Due to many hardcoded assumptions of tools/ existing in Chrome, this is only manageble solution to the problem. This first step only moves stuff not used by the build system or bots, and deletes a few unused directories.
