tracing: Initialize track events conditionally

If V8 is running in a context where Perfetto hasn't been initialized
(e.g., as part of mksnapshot), don't try to initialize track events
either.

Since perfetto::Tracing::IsInitialized() was only added recently, we
also roll Perfetto to the latest revision. This also requires updating
the proto_library GN template together with the underlying libprotobuf
dependency.
