> Introduces per-VM AVIC ID and helper functions to manage the IDs.
> Currently, the ID will be used to implement 32-bit AVIC IOMMU GA tag.
> 
> The ID is 24-bit one-based indexing value, and is managed via helper
> functions to get the next ID, or to free an ID once a VM is destroyed.
> There should be no ID conflict for any active VMs.
