Added trace event to broadcastIntentWithFeature.

Test: follow the steps below to test
1. Collect a boot trace using the trace config from company/teams/auto/embedded/framework/performance/tools/src/perfetto_trace_config.textproto.
2. Open the trace in Perfetto and query for a slice name with 'broadcastIntent' using
SELECT * FROM slice WHERE name glob '%broadcastIntent:%';
