[PATCH v3 1/3] qemu: Add capability for PCI high memory MMIO size

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.
