Reduce binary size (1.6MB -> 600K) by removing protos/trace:lite dep

This CL removes any dependency from {traced, traced_probes, perfetto}
to //protos/trace:lite. Neither of them really require such dependency
and it causes significant binary bloat due to all the hundreds
.pb.{cc,h} generated by libprotobuf for any possible trace packet.
Specifically:

traced_probes: needs only to depend on the "zero" protos, for writing.

traced: needs the official protobuf only for the following reasons:
  - Packet validation (e.g., trusted uid)
  - Directly injecting some special packets (TraceConfig, uid, clocks)
Neither of them requires really the hundreds trace packets. They
can just use TrustedPacket, which doesn't pull in the other packets.

perfetto: it requires only TraceConfig, but that is a separate smaller
target.
