Subject: check trace flags at loading [Bug #14702]

* iseq.c (iseq_init_trace): at ISeq loading time, we need to check
  `ruby_vm_event_enabled_flags` to turn on trace instructions.
  Seprate this checking code from `finish_iseq_build()` and make
  new function. `iseq_ibf_load()` calls this funcation after loading.

* test/ruby/test_iseq.rb: add a test for this fix.
