arm64: KVM: export the capability to set guest SError syndrome
For the arm64 RAS Extension, user space can inject a virtual-SError
with specified ESR. So user space needs to know whether KVM support
to inject such SError, this interface adds this query for this capability.
KVM will check whether system support RAS Extension, if supported, KVM
returns true to user space, otherwise returns false.
