libcamera: software_isp: Use floating point for color parameters
It's more natural to represent color gains as floating point numbers
rather than using a particular pixel-related representation.
double is used rather than float because it's a more common floating
point type in libcamera algorithms. Otherwise there is no obvious
reason to select one over the other here.
The constructed color tables still use integer representation for
efficiency.
Black level still uses pixel (integer) values, for consistency with
other libcamera parts.
