net/mlx5: SD, support switchdev mode transition with shared FDB

When the eswitch transitions, propagate the change to SD: secondaries
get their TX flow table root reconfigured for the new mode, and when
all group devices move to switchdev, the per-group shared FDB is
activated.

Shared FDB activation is best-effort - failure does not block the
eswitch transition; the next transition retries.

Note: the existing mlx5_get_sd() guard that blocks switchdev for SD
devices is intentionally retained. It will be removed once all
supporting patches are in place.
