remove rb_thread_t::event_hooks.

* vm_core.h (rb_thread_t): remove rb_thread_t::event_hooks.

* vm_trace.c: all hooks are connected to vm->event_hooks and
  add rb_event_hook_t::filter::th to filter invoke thread.
  It will simplify invoking hooks code.

* thread.c (thread_start_func_2): clear thread specific trace_func.

* test/ruby/test_settracefunc.rb: add a test for Thread#add_trace_func.
