Creates a new TaggedOperation, with this op and the specified tags.

This method can be used to attach meta-data to specific operations
without affecting their functionality. The intended usage is to
attach classes intended for this purpose or strings to mark operations
for specific usage that will be recognized by consumers. Specific
examples include ignoring this operation in optimization passes,
hardware-specific functionality, or circuit diagram customizability.
Tags can be a list of any type of object that is useful to identify
this operation as long as the type is hashable. If you wish the
resulting operation to be eventually serialized into JSON, you should
also restrict the operation to be JSON serializable.

new_tags – The tags to wrap this operation in.
