x86: Let x2APIC support depend on interrupt remapping or guest support
We are able to use x2APIC mode in the absence of interrupt remapping on certain hypervisors. So it is fine to disable IRQ_REMAP without having to give up x2APIC support.

This enables x2apic support on CPUs that have this feature.
