gic: Introduce virGICVersion enumeration

Browse Source 
We currently blindly accept any numeric value as a GIC version, even
though only GIC v2 and GIC v3 actually exist; on the other hand, we
reject "host", which is a perfectly legitimate value for QEMU guests.

This new enumeration contains all GIC versions libvirt is aware of.
