This series adds support for eGPUs on Apple products, by
enabling apple-set-os on all apple devices.

A side effect of this patch is that the iGPU becomes enabled on iMacs.
However, iMacs can’t use the iGPU to drive the display
(They can't link-train the internal display),
so displays must be disabled on iMacs.

Changes in v2:
- Reworded cover-letter
- Transferred logic to has_no_display in the 2nd patch
