perf/x86/intel: Add Cooper Lake stepping to isolation_ucodes[]
The intel_pebs_isolation quirk checks both model number and stepping.
Cooper Lake has a different stepping (11) than the other Skylake Xeon.
It cannot benefit from the optimization in commit 9b545c04abd4f
("perf/x86/kvm: Avoid unnecessary work in guest filtering").
Add the stepping of Cooper Lake into the isolation_ucodes[] table.
