Add consumer API and --query cmdline to list data sources
This CL adds a --query (and --query-raw) cmdline option to
the perfetto cmdline client to list the data sources connected
(whether they are tracing or not) and to retrieve the
DataSourceDescriptor passed at registration time.
--query returns a human readable format (for debugging).
It does NOT print the full DataSourceDescriptor (because
it might now know the schema)
Example: https://pastebin.com/cC9mAWw1
--query-raw is for machine-to-machine and passes through
the whole tracing_service_state.proto, including the
DataSourceDescriptor(s).
Bug: 132678367
Test: unittests + integrationtests
