[iOS][Translate] Moves legacy translate infobar EG tests to a new target

Moves the EG tests related to the legacy translate infobar to a new target
as the new infobar EG tests rely on the CompactTranslateInfobarIOS feature
to be enabled via command line which will break the legacy infobar tests.

- This CL does not make any changes to the tests logic.
- The new target is the previous translate_egtest target which runs on
  downstream bots.
