vfio: selftests: Add mlx5 driver - data path and memcpy ops
Complete the mlx5 driver by adding CQ/QP creation, QP state
transitions, WQE posting, CQ polling, and the
memcpy_start/memcpy_wait callbacks. After this patch the driver is
functional for DMA tests.
The data path implements RDMA Write self-loopback via an RC QP with
force-loopback. WQEs are posted to a 16-entry send queue with an
NC doorbell, and completions are polled from a 16-entry CQ.
