Move segment sorter to common (#5378) 
- move segment sorter to common
- this is the first of a handful of pr's that splits the larger pr #5326
- it moves this facility to common (from ranking objective class), so that it can be
    used for metric computation
- it also wraps all the bald device pointers into span.
