Add and use kvm_vcpu_is_legal_cr3() to check CR3's legality to provide a clear distinction between CR3 and GPA checks. This will allow exempting bits from kvm_vcpu_is_legal_cr3() without affecting general GPA checks, e.g. for upcoming features that will use high bits in CR3 for feature enabling. No functional change intended.
