Add tests for Ibb9eb9f65323795d139 and I6571d464a46453934f0

This CL adds several unit tests for following CLs, both of which enabled
InputMethodUtils (and dependent IMF logic) to handle 3 letter language codes
and conversion from deprecated two-letter codes to new ones correctly.
- Ibb9eb9f65323795d139b16d76b7e7e36a4e0568c
- I6571d464a46453934f0a8f5e79018a67a9a3c845

As described in tests, the input method framework has already been able to
recognize 3 letter language codes.  However, there remain inconsistencies
when we use deprecated 2-letter code to query subtype like "in" but the
subtype has new language codes like "id".  Subsequent CLs are supposed to
address remaining issues.
