tracing: Send triggers on connection The newly introduced ActivateTriggers only sends triggers to the currently connected backends. Since perfetto::Tracing::Initialize() is not blocking, it can happen that a backend takes a while to connect. If a registered backend is not connected when ActivateTriggers is called, the system will remember that and send the trigger when the backend connects. An expiration must be provided to avoid sending triggers if the tracing service takes too much to connect. Bug: 259929612 Change-Id: I183ef3ae04e960797adc835e137f854d0ebd409d
