vfio: Change default dirty pages tracking behavior during migration
By default dirty pages tracking is enabled during iterative phase (pre-copy phase). Added per device opt-out option 'x-pre-copy-dirty-page-tracking' to disable dirty pages tracking during iterative phase. If the option 'x-pre-copy-dirty-page-tracking=off' is set for any VFIO device, dirty pages tracking during iterative phase will be disabled.
