vfio/mlx5: Improve the target side flow to reduce downtime
Improve the target side flow to reduce downtime as of below.
- Support reading an optional record which includes the expected
stop_copy size.
- Once the source sends this record data, which expects to be sent as
part of the pre_copy flow, prepare the data buffers that may be large
enough to hold the final stop_copy data.
The above reduces the migration downtime as the relevant stuff that is
needed to load the image data is prepared ahead as part of pre_copy.
