Documentation: KVM: Update GICv3 docs for GICv5 hosts

Browse Source 
GICv5 hosts optionally include FEAT_GCIE_LEGACY, which allows them to
execute GICv3-based VMs on GICv5 hardware. Update the GICv3
documentation to reflect this now that GICv3 guests are supports on
compatible GICv5 hosts.

to inject interrupts to the VGIC instead of directly to CPUs. It is not
possible to create both a GICv3 and GICv2 on the same VM.
