Create common helpers functions for these computation. Source and destination buffer height may not be the same because alignment constraint are different so use destination height to compute chroma offset because we target this buffer as hardware output. To be able to use the helpers in both VP9 HEVC code remove dec_params and use context->bit_depth instead.
