VMX/Viridian: suppress MSR-based APIC suggestion when having APIC-V

When the CPU has the necessary capabilities, having Windows use
synthetic MSR reads/writes is bogus, as this still requires emulation
(which is pretty much guaranteed to be slower than having the hardware
carry out the operation).
