Check whether HDR_OUTPUT_METADATA property exists on a KMS connector. If
yes, pretend that EDID claims support for all EOTF modes and update the
head supported EOTFs mask accordingly. If not, then only SDR is
possible.

Parsing EDID to take monitor capabilities into account is left for
later.

HDR mode cannot be set without HDR_OUTPUT_METADATA.
