net/mlx5: Add IFC bits to support RSS for IPSec offload
This adds the capabilities, ipsec_next_header and inner/outer l4_type_ext fields to support RSS for the decrypted packets. These fields are specifically for firmware steering. HWS validation logic is updated to correctly handle the changes, ensuring the unsupported fields are not set. Besides, reserved_at_c4 is fixed to reserved_at_d4 to reflect the accurate offset within the structure.
