[gtk/matthiasc/color-profiles: 129/140] glcontext: Add api to query hdr support




commit 94bea15f514ce6abb7a3373b51790b0f3166c0a3

    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.
