vo_opengl: implement ARIB STD-B68 (HLG) HDR TRC
This HDR function is unique in that it's still display-referred, it just allows for values above the reference peak (super-highlights). The official standard doesn't actually document this very well, but the nominal peak turns out to be exactly 12.0 - so we normalize to this value internally in mpv. (This lets us preserve the property that the textures are encoded in the range [0,1], preventing clipping and making the best use of an integer texture's range) This was grouped together with SMPTE ST2084 when checking libavutil compatibility since they were added in the same release window, in a similar timeframe.
