Handle SIGABRT properly in evs_app

- Avoid self-joining situation by checking the thread id
- Remove unnecessary IEvsEnumerator::closeDisplay() call from the
  signal handler
- Restart automotive_display service on evs_sample_driver service's
  restart
- Modify evs_app to hold a weak reference to an IEvsDisplay object

Fix: 193664888
Test: Manually kill evs_sample_driver service by sending SIGTERM while
      evs_app is running and confirm no error messages reported on the
      bug

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
