[roll] Roll fuchsia [fuchsia_base_test] Add option to collect traces

This change adds the ability for developers to add the 'tracing_on'
param to mobly tests similar to 'snapshot_on'. FuchsiaBaseTest will then
initialize, start, stop and terminate the trace depending on the desired
frequency (teardown_test, teardown_class...)
