[libvirt PATCH v2 10/22] DONOTMERGEYET: qemu: Introduce QEMU_CAPS_VIRTIO_IOMMU_BOOT_BYPASS

This capability detects the availability of the boot-bypass property of the virtio-iommu-pci device. This property was only introduced in QEMU 6.2 but, since the device has been around for much longer, we end up querying its properties for several more releases. As I don't have convenient access to the 10+ binaries necessary to regenerate the replies, I just put some fake data in there. NOTE: the QEMU 6.2 binaries were built from source trees where https://lists.gnu.org/archive/html/qemu-devel/2021-10/msg00161.html https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg07819.html had been applied.
