[X86] Fix Store AGU/Memory ports on IceLakeServer model

[X86] Fix Store AGU/Memory ports on IceLakeServer model

The IceLakeServer model was directly copied from SkylakeServer model and we didn't do much to adjust the changes in port layout etc.

IceLake handles all store AGU on ports 7/8 (and not 2/3/7 like Skylake), store memory ops are handled on ports 4/9 (and not just port 4)

Fixes #62602
