Paravirt features is enabled by default if it is supported by KVM host,
such as KVM_FEATURE_IPI and KVM_FEATURE_STEAL_TIME, however paravirt
feature KVM_FEATURE_VIRT_EXTIOI is controlled from qemu VMM rather KVM
host.
>From qemu VMM side, all paravirt features should be controlled. Here
property of paravirt features are added, also feature detection and
enabling is added here.

v1 ... v2:
1. Add stub implementation with kvm_loongarch_cpu_post_init() so that
it passes to compile with --without-system option.
2. In order to detect supported paravirt features from qmp command,
paravirt feature is added in array cpu_model_advertised_features
such as kvm-pv-ipi and kvm-steal-time.
