Architectures such as arm64 and riscv uses vcpu variables
such as has_run_once and ran_atleast_once, respectively,
to mark if the vCPU has started running. Since these are
architecture agnostic variables, introduce
kvm_vcpu_has_run_once() as a core kvm functionality and
use this instead of the architecture defined variables.

No functional change intended.

arm64 is moving away from this, see [1]. You also don't need any new
state, as vcpu->pid gives you exactly what you need.

Happy to queue additional patches on top if you want to deal with
riscv.

Thanks,
