[RFC PATCH-for-9.0 11/11] hw/intc/meson: Simplify how arm_gicv3_kvm.o objects are built

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Use the target_aarch64_available() to build the ARM_GIC_KVM types
regardless the ARM/AARCH64 targets are selected, but restrict its
registration to TARGET_AARCH64 presence at runtime.

This will help to have a single binary running both ARM/Aarch64.
