efl: Add missing event types

Summary:
All events must have a type now, otherwise bindings don't know how to handle
the event_info field.
Most of the missing event types were actually "void" (no event_info present).
Some struct definitions had to be moved to eo instead of h files, so they
are available to bindings. Some have not, and are marked with FIXME.
Some namespaces have been fixed (like Efl_Event_Cb -> Efl.Event_Cb).

In general, there are hundreds of changed files, but mostly to add a type which
was not present before, so there's no harm done.
Also, A lot of FIXMEs have been added which should be, like, fixed.
For example, some events can send different types of event_info, which is
very inconvenient (and error prone).

Test Plan: make with c# bindings works, make check and make examples work too.
