tracing: Move raw_init from events to class

The raw_init function pointer in the event is used to initialize
various kinds of events. The type of initialization needed is usually
classed to the kind of event it is.

Two events with the same class will always have the same initialization
function, so it makes sense to move this to the class structure.

Perhaps even making a special system structure would work since
the initialization is the same for all events within a system.
But since there's no system structure (yet), this will just move it
to the class.

   text    data     bss     dec     hex filename
4913961 1088356  861512 6863829  68bbd5 vmlinux.orig
4900375 1053380  861512 6815267  67fe23 vmlinux.fields
4900382 1048964  861512 6810858  67ecea vmlinux.init

The text grew very slightly, but this is a constant growth that happened
with the changing of the C files that call the init code.
The bigger savings is the data which will be saved the more events share
a class.
