net/mlx5_core: New device capabilities handling
- Query all supported types of dev caps on driver load. - Store the Cap data outbox per cap type into driver private data. - Introduce new Macros to access/dump stored caps (using the auto generated data types). - Obsolete SW representation of dev caps (no need for SW copy for each cap). - Modify IB driver to use new macros for checking caps.
