Let lossdetectioninterface::detectlosses to return a detectionstats which includes the max sequence reordering observed from acked packets. protected by existing flag --gfe2_reloadable_flag_quic_enable_loss_detection_experiment_at_gfe.
The previous change, cl/309076773, used number of reordered _incoming_ packets to decide whether to send feedback to reordering_threshold_session. This CL changed it to use maximum reordering from _acked_ packets instead.
