Add perfetto build config 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.

Convert decoder TRACE_EVENT to flows This is the first new style trace event so this CL adds and updates WebRTCs Perfetto configuration. * Changes all #includes to target "third_party/perfetto". Added this to DEPS. * Expose the Perfetto public config in the "tracing" group using an all_dependent_configs statement. This means the config is included in all parts that include the "//:tracing" group. However, direct perfetto includes are banned per DEPS. * In order to expose Perfetto types (ie Flow/TerminatingFlow) the perfetto headers are a dependancy on all targets. This should not affect binary size as these are not used when perfetto is not enabled and will not be linked.
