store ec instead of thread in rb_context_t.

* cont.c (rb_context_t): introduce saved_ec instaad of saved_thread.
  We only need to transfer ec data (not all of thread data).

  Introduce `thread_value` field to point creation thread.
  To acccess this field, `cont_thread_value()` is introduced.

* vm.c (rb_execution_context_mark): remove `static` and use it
  from cont.c (use this function instead of `rb_thread_mark`).

* vm_insnhelper.c (rb_vm_push_frame): accept ec instead of th.
