fix: avs registrar interface

[8sunyuan]

Motivation:

Currently there is no way for an AVS implementing these callback functions of the IAVSRegistrar.sol to verify that the operatorSetIds belong to their operatorSets. This is because AVSRegistrar configuration does not have uniqueness and implementing uniqueness in the AllocationManager is not feasible due to frontrunning DOS vectors for existing AVSs.

Modifications:

IAVSRegistrar.sol interface

Result:

• Allowing AVSs to verify the correct operatorSet is being passed into their register/deregister callback functions and whether or not to proceed with the Operator action.
• Downstream breaking interface changes for AVSs

LGTM - needs to pass CI + tests though. Is there a MW PR too?
