Geoffrey McRae 20225f05d1 [idd] hdr: complete HDR display and cursor metadata ...

Publish BT.2020 chromaticities in the virtual monitor EDID so
Windows receives a valid HDR colour volume.

Extend cursor messages with their IddCx SDR white level and an
explicit visibility-valid flag. Consumers can then calibrate cursors
without treating colour-transform-only messages as cursor hides.
