This commit adds test coverage for the multitouch input device feature.

Updated test files to get this new capability working with other input
devices:
- tests/qemucapabilitiesdata/caps_10.2.0_x86_64.xml: Adds the
  QEMU_CAPS_VIRTIO_MULTITOUCH capability to the QEMU 10.2.0 capability
  test data, indicating that this QEMU version supports multitouch devices.

- tests/qemuxmlconfdata/virtio-input.xml: Adds a multitouch input device
  definition to the virtio-input test case, providing an example of proper
  XML syntax.

- tests/qemuxmlconfdata/virtio-input.x86_64-latest.xml: Updates the expected
  parsed XML output to include the multitouch device configuration.

- tests/qemuxmlconfdata/virtio-input.x86_64-latest.args: Updates the expected
  QEMU command-line arguments to include the virtio-multitouch-pci device,
  validating that libvirt correctly translates the XML into QEMU arguments.
