net/mlx5: DR, Use the new HW specific STE infrastructure

Browse Source 
Split the STE builders functionality into the common part and
device-specific part. All the device-specific part (with 'v0' in
the function names) is accessed through the STE context structure.

Subsequent patches will have the device-specific logic moved to a
separate file.
