Add display feature discovery subtests for HDR, VRR and DSC.

HDR requires:
- IGT_CONNECTOR_MAX_BPC with max bpc >= 10
- IGT_CONNECTOR_HDR_OUTPUT_METADATA
- EDID HDR capability via igt_is_panel_hdr()

VRR checks connector vrr_capable support.
DSC checks sink support via igt_is_dsc_supported_by_sink().
