mellanox: enable DDI on VFs via VFConfigHook

Add a VFConfigHook extension point to SriovInterface that vendor plugins
can register to inject per-VF logic after unbind. The Mellanox plugin
registers MellanoxVFHook, which enables DDI (Data Direct Interface) on
VFs whose PF is configured with flow_steering_mode=hmfs (Spectrum-X).

The hook loads the fwctl/mlx5_fwctl kernel modules if absent, then calls
doca_mgmt_data_direct set. Unsupported NICs (no fwctl sysfs entry or
firmware rejection) are soft-skipped without failing the SR-IOV flow.

doca_mgmt_data_direct is compiled from the DOCA samples bundled in the
base image and copied into the NVIDIA config-daemon container image.
No CRD changes are required; the existing flow_steering_mode=hmfs
devlink param serves as the DDI opt-in signal.
