[X86] Split Cannonlake + Icelake Tuning. NFC

The Ice/Tiger/RocketLake specs were inheriting the tuning settings from CannonLake, a previous architecture. We shouldn't have this dependency, so I've copied the current tuning settings so we can make future adjustments to both CNL + ICL etc. more easily.
