net/mlx5: E-Switch, Move representors definition to a global scope

Browse Source 
In preparation for IB representors, move representors structs to a global
scope, also expose functions needed for registration, unregistration,
eswitch mode and creating a flow rule to direct traffic from SQs to the
right VF.
