Take advantage of the kernel flush for dirty bo in the busy ioctl
Rather than just creating and submitting a batch that simply contains a
flush in order to periodically ensure that rendering reaches the
scanout, we can simply ask the kernel whether the scanout is busy. The
kernel will then submit a flush on our behalf if it is dirty, which
takes advantage of the kernel's dirty state tracking.
