add ids for Intel Xeon Scalable

add ids for Intel Xeon Scalable

Used by at least Skylake-SP (SKX) and Cascade Lake-SP (CLX).

Covers Xeon Scalable, Xeon D, Xeon W, Core Extreme/Core X product
families.  The Scalable parts are marketed as Xeon Bronze, Silver, Gold
and Platinum.

As most of these ids are not described in public documents from Intel
use Skylake-ESystem.inf and KabyLakePCH-HSystem.inf from Intel's Windows
drivers to get an idea of what the names should be.  With the name for
0x2088 found in a Intel authored Linux driver.

Initial patch and much discussion from Karel Gardas.
