net/mlx5: SD, introduce Socket Direct LAG

Browse source

Register SD secondary devices with the existing LAG structure by
adding them to the primary's ldev xarray with a shared group_id.
This ties the SD LAG lifecycle to the SD group lifecycle.

Add sd_lag_state debugfs entry for LAG state visibility. To avoid
race between this entry and LAG deletion, have debugfs creation
and deletion done last on SD init and first on SD cleanup.
