UefiCpuPkg/MpInitLib: Always use AP Create if GhcbApicIds HOB is present
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654
Currently, the first time an AP is started for an SEV-SNP guest, it relies
on the VMSA as set by the hypervisor. If the list of APIC IDs has been
retrieved, this is not necessary. The list of APIC IDs will be identified
by a GUIDed HOB. If the GUIDed HOB is present, use the SEV-SNP AP Create
protocol to start the AP for the first time and each time thereafter.
