Streamline legacy gradient color conversion

To produce colors for interpolation in legacy mode, we currently do
something like

  SkColor c = Sk4f_toS32(swizzle_rb(Sk4f::Load(c4f)));
    color4f = swizzle_rb(SkNx_cast<float>(Sk4b::Load(&c)) * (1/255.0f));

Let's see if we can streamline some of that.
