tracing: Convert some workqueue events to DEFINE_EVENT
Use DECLARE_EVENT_CLASS to remove duplicate code:
text data bss dec hex filename
13171 800 72 14043 36db kernel/workqueue.o.old
12243 800 68 13111 3337 kernel/workqueue.o
Two events are converted:
workqueue: workqueue_insertion, workqueue_execution
No change in functionality.
