Make the intra rd search support 8x4/4x8 This commit allows the rate-distortion optimization of intra coding capable of supporting 8x4 and 4x8 partition settings. It enables the entropy coding of intra modes in key frame using a unified contextual probability model conditioned on its above/left prediction modes. Coding performance: derf 0.464% Change-Id: Ieed055084e11fcb64d5d5faeb0e706d30268ba18
