Replaces SyncChannel::Send, RenderProcessHostImpl::Send, and GpuChannelHost::Send trace events with typed trace events. Also adds a utility to convert the IPC class ID to a corresponding protobuf enum. Corresponding proto buffer definitions for these events were added in aosp/1180211. Typed trace events will allow inclusion of the event arguments in slow reports data in the future. The trace format is protocol-buffer based under the hood already (see docs.perfetto.dev for details), this patch adds strong typing for the arguments of the respective events only.
