Takaya Saeki a150978ca0 devices: virtio: video: make Worker async friendly 
Update `Worker` of the video device to make it easier to add async run
method; separate the interrupt into two `SignalableInterrupt`s for the
command/event queues, and move `Event`s to outside `Worker`. These are
changes preparing for introducing `run_async` method to `Worker`.
`run_async` will need separate Interrupts for the command queue and the
event queue, and will not need `Event`s inside `Worker`.

BUG=b:179756087
TEST=simple_decoder test script (see the crosvm book) worked with and
without -p "pci=nomsi" guest kernel parameter, which triggers interrupt
resample by disabling MSI-X interrupt.

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.
