drm: Add xe_pciids.h
Add header with PCI IDs to which the xe driver will bind to. This is a copy of i915_pciids with a few differences:
- Only the platforms supported by xe are added
- It declares the lists in a generic way so they can be used for
things other than creating an array of struct pci_device_id
