If PCID is not exposed to the guest, clear INVPCID in the guest's CPUID even if the VMCS INVPCID enable is not supported. This will allow consolidating the secondary execution control adjustment code without having to special case INVPCID. Technically, this fixes a bug where !CPUID.PCID && CPUID.INVCPID would result in unexpected guest behavior (#UD instead of #GP/#PF), but KVM doesn't support exposing INVPCID if it's not supported in the VMCS, i.e. such a config is broken/bogus no matter what.
