macOS Hypervisor.framework uses different types for identifying vCPUs,
hv_vcpu_t or hv_vcpuid_t, depending on host architecture. They are not just
differently named typedefs for the same primitive type, but reference
different-width integers.

Instead of using an integer type and casting where necessary, this change
introduces a typedef which resolves to the active architecture’s hvf typedef.
It also removes a now-unnecessary cast.
