    Make palette work correctly with chroma sub8x8 blocks. · c9e71d4d
    Urvang Joshi authored
    The problem was that some functions were using scale_chroma_bsize()
    function to turn sub-8x8 'bsize' to 8x8 'bsize', and then the modified
    'bsize' was being passed to rd_pick_intra_sbuv_mode() for example.
    
    In such cases, we cannot rely on the 'bsize' value passed to the
    function; instead, we need to look at the original mbmi->sb_type
    directly.
    
    Also:
    - Added created a common function can_use_palette() to refactor this
    logic into one place.
    - Added more asserts to easily catch such coding errors in future.
