Remove BT.2020 support from QColorSpace

BT.2020 is an HDR color space and its luminance range doesn't match
that of the rest of the currently available color spaces. Without
support for white-point luminance in 5.14, there would be a behavior
change when luminance support is later introduced, so it is better to
remove it now, and reintroduce it when the necessary handling of
different luminance levels is available.
