    [NTUSER] Fix SPI_SETFONTSMOOTHING behavior (#5526)
    
    CORE-19092
    
    Fixes the behavior of the SPI_SETFONTSMOOTHING system parameter. This also
    fixes a bug when trying to select "Use the following method to smooth edges
    of screen fonts" in desk.cpl.
    
    Instead of checking if uiParam is equal to two, treat uiParam as a Boolean
    that sets font smoothing on or off. This is the correct behavior according
    to Microsoft documentation.
    Use SpiStoreSzInt method instead of SpiStoreSz to store the value in the registry.
