    Removes the COGL_PIXEL_FORMAT_{24,32} defines
    
    Although these are in the public headers we should assume that no one is
    using them since they were never documented so no could know what they
    are useful for.
    
    If you were to guess you'd be forgiven for thinking they were bitmasks
    for checking some flags to see if a format is 24 or 32 bits. If you
    looked further you might instead be forgiven for thinking that if you
    masked of the least significant nibble of a pixel-format then you could
    check the value against these defines. Neither of the previous
    operations are reliable ways to check if a format is 24 or 32bit and
    instead code must use then internal
    _cogl_pixel_format_get_bytes_per_pixel() api if they want to know the
    pixel size for a given format which relies on a 16 entry lookup table
    using the least significant nibble of a pixel-format.
