remove do_queue argument from Operation.adjoint

[albi3ro]

The Operation.adjoint method currently has a do_queue keyword that is not used for anything and is usually left out of child implementations.

This PR standardizes the removal of the do_queue keyword.

Looks pretty straight forward! Would this be removing the ability to control if an adjoint operation is queued completely, or would we just move that functionality to the Adjoint wrapper class?

It might be good to check (I'm not sure) if there are any tests that need to be updated or removed that check for queuing of the adjoint of these operations. But other then that I think its good to go

Obviously, this keyword was completely untested, as I could remove it without breaking any tests. Also, the most common operations already had it removed, leading to lots of manually silenced linting complaints.
