Implement kvm_arch_vcpu_async_ioctl() "natively" in x86 and arm64 instead of relying on an #ifdef'd stub, and drop HAVE_KVM_VCPU_ASYNC_IOCTL in anticipation of using the API on x86. Once x86 uses the API, providing a stub for one architecture and having all other architectures opt-in requires more code than simply implementing the API in the lone holdout. Eliminating the Kconfig will also reduce churn if the API is renamed in the future (spoiler alert). No functional change intended.
