virtio: video: add support for guest memory

Supporting guest memory is necessary for many guests that expect to
render into guest-allocated memory (as opposed to the virtio-object
method that is for now rather specific to Chrome OS). Add support for
this kind of memory in the form of SG lists.

BUG=b:209523781
TEST=Android Youtube plays properly on Hatch.
TEST=v4l2r's test decoder can allocate MMAP buffers.

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.
