HDR display support -- HDR compatible configs

As presented at the Siggraph BoF, we propose having a set of characteristics that configs must support to be considered "HDR display compatible".

The proposed characteristics are:
- Must the set `cie_xyz_d65_interchange` role to allow applications to convert to OS-required space
- Must use display color spaces
- Must set `interop_id` on display color spaces
- Must include the hdr_virtual_display (see forthcoming proposal)

A new function `Config::isHdrDisplayCompatible()` will be provided for applications to use.

The `ociocheck` command-line tool will be upgraded to report if a config is HDR display compatible.

Parent issue: #1996.

Start by reviewing parent issue #1996 and the forthcoming hdr_virtual_display proposal. Trace the Config::isHdrDisplayCompatible() entry point and the ociocheck command path. Done means configs are checked against the listed HDR compatibility characteristics and ociocheck reports the result.
