virtio: video: expose backend name to guest

Knowing the decoding method used on the host can be useful to the guest,
e.g. in order to decide which format to use for buffers or to choose
between several acceleration options if more than one decoder or encoder
device exists.

Since this change only adds additional data to the device configuration
space, it does not introduce any incompatibility with existing guests.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
