Rob Bradford eb4dd90532 arch: x86_64: Avoid calling cpuid for setting LAPIC ID ...

Rather than calling cpuid and then updating the APIC ID field - use the
existing common CPUID data which already includes CPUID data for eax=1
(aka function = 1).  This removes the need to call cpuid per vCPU thread
created. This has a positive impact on boot time with multiple vCPUs as
the cpuid instruction is serialising.

Fixes: #5646
