perf tools: Add debug prints for ordered events queue
Adding some prints for ordered events queue, to help debug issues.
Adding debug_ordered_events debug variable to be able to enable ordered
events debug messages using:
$ perf --debug ordered-events=2 report ...
Also using oe pointer in perf_session__queue_event instead of chained
session variable dereferencing.
