x86/cpu: Add Comet Lake to the Intel CPU models header

[ Upstream commit 8d7c6ac3b2371eb1cbc9925a88f4d10efff374de ]

Comet Lake is the new 10th Gen Intel processor. Add two new CPU model
numbers to the Intel family list.

The CPU model numbers are not published in the SDM yet but they come
from an authoritative internal source.
