libs: encoder: h264: Add machinery for implementing hierarchical-prediction
Adds some basic building blocks to ease the implementation
of hierarchical prediction modes.
-- add an utility method to find temporal level of each frame
-- define max_ref_frame count based on temporal level count
-- add temporal_level_div[] for finding temporal level each frame
to be encoded.
-- find ip_period based on temporal level count
