Add QEMU capability for PCI high memory MMIO size configuration:
- Add QEMU_CAPS_MACHINE_VIRT_HIGHMEM_MMIO_SIZE capability
- Add capability to virt machine properties
- Add highmem-mmio-size virt machine property to aarch64 qemu
10.0.0 capabilities
This allows detecting support for the highmem-mmio-size virt machine
property in QEMU.
