Sebastian Jansson 1d430f727d Interface for packet feedback availability in SSCC
This CL adds a function to the SendSideCongestionController interface
for reporting per packet feedback availability.

This is part of a series of CLs tracking the transport feedback status
of the streams known to BitrateAllocator and reporting the status to
the congestion controller.
