Negative infinity is useful in comparisons as it represents a value
guaranteed to be less than any other timestamp. This avoid using
Timestamp::ms(0) to represent such a value or having to use optional
for the special case of first time execution.
To avoid ambiguity, Timestamp::Infinity is renamed to PlusInfinity.

This adds a start bitrate field to TargetRateConstraints since this is
required in VideoSendStreamTests. This also reduces the differences
between the old SendSideCongestionController and the new TaskQueue
based version.

The loss rate is used to control error correction. Previously the value
was reported as zero which would disable error correction.

The BBR controller did not properly report updates to congestion
windows. This was due to a check to avoid the overhead of callbacks.
In the current design without callbacks in the controller, the check can
be removed. If helpful for performance, it should live outside of the
controller.

This CL adds a field trial to enable the BBR congestion control method.
Since BBR is only implemented to handle per packet feedback,
SendSideCongestionController is modified to recreate network controllers
when the packet feedback availability changes and the BBR experiment is
enabled.
This also means that the periodic task used for process updates in the
network controllers has to recreated.
