Jonah Williams f64d4f6eb7 [Impeller] Switch back to using explicit flush for device buffers. (flutter/engine#43644) ...

Not all devices support the host_coherent + host_visible + device_local combo (though most do). I believe this change was associated with a slight regression in performance, so back it out and go back to flush to see if that improves things.
