x86/cpu: Add Xeon Emerald Rapids to list of CPUs that support PPIN (2023-04-05 20:01:52 +0200)

----------------------------------------------------------------
- Add Emerald Rapids to the list of Intel models supporting PPIN

- Finally use a CPUID bit for split lock detection instead of
enumerating every model

- Make sure automatic IBRS is set on AMD, even though the AP bringup
code does that now by replicating the MSR which contains the switch

----------------------------------------------------------------
