pw_kvs: Fix AlignedWrite issues; expand tests

- Update AlignedWriter to prevent writing after an error occurs.
- Ensure that the number of written bytes is always returned for
  AlignedWriter errors.
- Remove FlashError::Mode, since the number of bytes affected should
  always be set.
- Add tests to alignment_test.cc and key_value_store.cc to cover
  failures during AlignedWrite.
- Update some comments.
