Update VideoStreamEncoder to use new VideoEncoder::SetRates() method.

This CL wires up the new SetRates() method of the video encoders, and
refactors a few things in the process:

Most notably, the VideoStreamEncoderInterface is update so that the
|target_headroom| parameter is replaced with |link_allocation|, meaning
that instead of indicating bitrate capacity in excess of the target
bitrate, it indicates to total network capacity allocated for the
stream including the target bitrate. This matches the VideoEncoder API.

The VideoEncoder::RateControlParameters struct gets a few new helper
methods.

In VideoStreamEncoder, instead of adding more fields to the
|last_observed_bitrate*| family, uses an optional struct that
inherits from VideoEncoder::RateControlParameters.
