tracing: Convert some kmem events to DEFINE_EVENT
Use DECLARE_EVENT_CLASS to remove duplicate code:
text data bss dec hex filename
333987 69800 27228 431015 693a7 mm/built-in.o.old
330030 69800 27228 427058 68432 mm/built-in.o
8 events are converted:
kmem_alloc: kmalloc, kmem_cache_alloc
kmem_alloc_node: kmalloc_node, kmem_cache_alloc_node
kmem_free: kfree, kmem_cache_free
mm_page: mm_page_alloc_zone_locked, mm_page_pcpu_drain
No change in functionality.
