vdpa_sim_blk: add support for VIRTIO_BLK_T_FLUSH
The simulator behaves like a ramdisk, so we don't have to do
anything when a VIRTIO_BLK_T_FLUSH request is received, but it
could be useful to test driver behavior.
Let's expose the VIRTIO_BLK_F_FLUSH feature to inform the driver
that we support the flush command.
