color_management_v1: add create windows scrgb

Browse source 
v2: Remove assert blocking feature, gate feature behind compositor
    enabling it, and set get_info_allowed to false for the
    descriptor returned
v3: Whoops, made a minor error without testing it first. Thanks, CI.
v4: Add default luminance level response for linear color. Thanks,
    Dominick DiMaggio @njdom24
v5: Revert v4, and instead use new implementation of
    set_luminances to apply a color luminance range
v6: Move luminances declaration to the correct place
