[gtk/matthiasc/color-profiles: 10/12] glcontext: Add api to query hdr support

[Matthias Clasen <matthiasc src gnome org>]

commit 3236de2cc3b3b97324eff3d53b5db4107f083ed9

    glcontext: Add api to query hdr support
    
    Add private api to find out if we have an fbconfig
    for HDR framebuffers.
    
    Currently this does nothing, since no backend implments
    the vfunc yet.
