x86/cpuid: add CPUID flag for Extended Destination ID support
Introduce the CPUID flag to be used in order to signal the support for
using an extended destination ID in IO-APIC RTEs and MSI address
fields. Such format expands the maximum target APIC ID from 255 to
32768 without requiring the usage of interrupt remapping.
The design document describing the feature can be found at:
