perf timechart: Remove event types framework only user

The only user of the event types data is 'perf timechart' command and
uses this info to identify proper tracepoints based on its name.

Switching this code to use tracepoint callbacks handlers same as another
commands like builtin-{kmem,lock,sched}.c using the
perf_session__set_tracepoints_handlers function.

This way we get rid of the only event types user and can remove them
completely in next patches.
