[tracing] Use ChromeTracePacket to save binary size with perfetto
Previously, compiling with perfetto would add 2.3 MiB to the d8 release binary. With this change it's 472 KiB. This is because trace:lite pulls in many more compiled proto classes than we need, e.g. a bunch of stuff under ftrace/ which is only used on Android. Chrome uses a 'mirror proto' ChromeTrackPacket to only provide compiled protos for the types of packets it will actually see, which on non-android devices does not include anything under ftrace/. We use the same trick here in the JSON consumer.
