core/debug-control: Add new ForceHDR debug control

Browse Source 
It will be used to force the color state of all monitors to be as if
they managed to turn on HDR mode. This is useful for debugging shaders
in an environment where an HDR mode capable display is not available,
such as the nested mode.
