We want to avoid system clock dependencies in congestion
controllers as it makes it harder to test them. This CL removes
a rtc::TimeMillis() call from the AlrDetector class and removes
dependencies on rtc_base_approved as it exposes time_utils.h.

Originally RtcEventProbeClusterCreated was logged in bitrate prober. This means that anyone who was using GoogCcNetworkControl wasn't logging it, and the NetworkControl wasn't self-contained.
This changes moves the responsibility for logging ProbeClusterCreated to ProbeController (where the probe is created), it also moves the responsibility for assigning probe ids to the probe controller.

The new controller behaves mostly like before, but increases the target
rate on timer update rather than when feedback is received. This makes
the behavior easier to predict. It also uses a duration parameter to
track the increase, removing the meed for the minimum rate increase
constants that exists in the previous solution.

This removes the old version of Probe Controller. The new controller is
slightly different, therefore the legacy SendSideCongestionController is
changed to accommodate the new function.
Most notably, the functionality is changed so that probes are now sent
only from the OnProcess call and not immediately on changing a
parameter.
The lock previously owned and used by ProbeController is moved to SendSideCongestionController. This should not change any
behavior.
