Add color spaces for CIF `g22_adobergb_display`, `g26_xyzd65_display`, `pq_xyzd65_display`

I don't know if we've ever explicitly discussed this, but _if_ the Studio config intends to provide implementations of all the color spaces described by the current [CIF Color Space Encodings for Displays](https://docs.google.com/document/d/1MmBG4a3Dr6S6EO781WjK-xZW7QdHpuo-zd7wtMvG1Rs) guidelines, we should add `g22_adobergb_display`, `g26_xyzd65_display`, and `pq_xyzd65_display` display color spaces.

(I feel like we've discussed and dismissed the idea of adding DCDM Displays, but I'm not sure if we dismissed adding display color spaces, per se, or whether those discussions took place before the CIF guidelines were authored)

Start by reviewing the CIF Color Space Encodings for Displays guidelines linked in the issue and inspect how the Studio config currently defines display color spaces. Confirm whether the config scope includes these encodings, then add implementations for the three named color spaces and verify that the configuration accepts them.
