[cogl/cogl-latest-win: 3/27] cogl/cogl-bitmask.h: Use size_t instead of unsigned long

    cogl/cogl-bitmask.h: Use size_t instead of unsigned long
    
    Using unsigned long is not safe as sizeof(long) is not necessary
    sizeof(void*) on some platforms, such as Windows on Visual Studio.  To
    avoid this, use size_t instead of unsized long, and use the correct
    unsigned suffix accordingly.
