MLIA-599 Enable testing for aarch64: unit tests

- mypy issue: to make the comment #type: ignore platform specific,
  flags like platform.machine() cannot be recognized by mypy, so we
  cannot isolate the specific lines of code that fail mypy tests
- numpy issue: for numpy version < 1.20, the function np.unique
  has not been type annotated, which caused mypy throwing the error
  when we run our unit tests in aarch64
- because of the above two reasons, we use function decorator to
  turn off type checking for entire functions to remove all
  annotations so that the mypy error for certain lines can be silented
