[RFCv2 15/38] x86/boot: move and rename sched_setup_dom0_vcpus

["Daniel P. Smith" <dpsmith@xxxxxxxxxxxxxxxxxxxx>]

Relocated the function sched_setup_dom0_vcpus(), which was protected by an
ifdef CONFIG_X86, from common/sched to the hyperlaunch domain builder. Rename
it to alloc_dom_vcpus() to better reflect the purpose of the function.
