Use BT2100 OOTF for HLG...
...which it turns out we already do, except we apply a tone-map for
HDR10 after scaling the luminance. Don't apply the HDR10 tone-map, and
instead linearly normalize to max display luminance.
Furthermore, adjust the gamma used in the default HLG OOTF in
libshaders to take into account current display luminance according to
the BT2100 spec, which says that the OOTF gamma should be adjusted if
the effective luminance differs from 1000 nits
