This adds Perfetto support to WebRTC with a GN flag rtc_use_perfetto. The configuration of perfetto depends on whether or not webrtc is build within Chrome or not. When in Chrome, WebRTC will depend on //third_party/perfetto:libperfetto. When building standalone, specific includes required for Perfetto are exposed with the library webrtc_libperfetto. The perfetto trace API is exposed with a header export in trace_event.h which is used instead of the legacy API. The addition of Perfetto means there are 4 compilation modes for tracing in WebRTC, 1. No tracing implementation. 2. Legacy tracing (AddTraceEvent/GetCategoryEnabled). 3.a. Perfetto statically linked (webrtc_libperfetto). 3.b. Perfetto in Chrome (Chrome's libperfetto). This CL removes the tracing expectations from rtc_stats_integrationtest.cc because those directly used the old API. Integration into Chrome is a follow up CL which depends on https://chromium-review.googlesource.com/c/chromium/src/+/5471691. Tested: Ran Chrome with Perfetto and traces appear.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
