net/mlx5: LAG, factor out shared FDB code into dedicated file

Browse source

Refactor shared FDB LAG logic into a new lag/shared_fdb.c file to
improve code organization and enable reuse. Move shared FDB specific
functions from lag.c and introduce consolidated APIs:
- mlx5_lag_shared_fdb_create() handles LAG activation with shared FDB
- mlx5_lag_shared_fdb_destroy() handles LAG deactivation with shared FDB

Update mlx5_do_bond(), mlx5_disable_lag() and mpesw.c to use the new
APIs, which simplifies the shared FDB code paths.
