KVM: arm64: Explicitly map 'kvm_vgic_global_state' at EL2

The pkvm hypervisor at EL2 may need to read the 'kvm_vgic_global_state'
variable from the host, for example when saving and restoring the state
of the virtual GIC.

Explicitly map 'kvm_vgic_global_state' in the stage-1 page-table of the
pKVM hypervisor rather than relying on mapping all of the host '.rodata'
section.
