linuxkpi: Define VFM_*() macros in <asm/cpu_device_id.h>

They use another set of constants and macros in <asm/intel-family.h>.

All these macros are defined regardless of the architecture, even though
they are specific to x86. Perhaps we should restrict them using #ifdefs.

The amdgpu DRM driver started to used VFM_MODEL() and the
INTEL_*LAKE* constants in Linux 6.12.x.
