Include tags in trace data.
The tags item in the trace data is arbitrary metadata added to `build`
steps by Soong (and my Kati via `.KATI_TAGS` target-specific
variables). Include this in the perfetto trace so we can analyze it.
Bug: http://b/259130368
Test: End to end test tracing cp time in dist targets
