Add rate utilization tracker helper class.

This class measures the allocated cumulative byte budget (as specified
by one or more rate updates) and the actual cumulative number of bytes
produced over a sliding window.

A utilization factor (produced bytes / budgeted bytes) is calculated
seen from the first data point timestamp until the last data point
timestamp plus the amount time needed to send that last data point
given no further updates to the rate.

Wireup to EncoderBitrateAdjuster will happen in a follow-up CL.
