    Account for 1-D/2-D transform kernels for the eob modeling. To
    maintain a smaller context cardinality, set the two 1-D transform
    kernels in the same category. The difference in directions should
    be largely covered by the scan order.
    
    This and the previous CLs on nz_map context modeling together
    improve the compression performance of level-map coefficient coding
    system by 0.4% for lowres.
