Add functions to calclulate the DFM parameters for the given frl config, which is further used to evaluate the data flow metering requirement as specified in the spec. As per the spec the below patches implement the frl capacity computation functions for both compressed and uncompressed video. Finally exposing 1 function each for compressed and uncompressed video to figure out if the data flow metering requirement is met or not.
