media: cros-codecs: factorize dummy backends The dummy backends behave the same regardless of the codec, so factorize their declaration as well as their implementation of VideoDecoderBackend to avoid duplicate code.

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.
