net/mlx5_core: Add more query port helpers

Browse Source 
Add the following helpers:

1. mlx5_query_port_proto_oper -- queries the port speed port mask
2. mlx5_query_port_link_width_oper - queries the port link with bitmask
3. mlx5_query_port_vl_hw_cap - queries the Virtual Lanes supported on this port

These helpers will be used from the IB driver when working in ISSI > 0 mode.
