[SPARK-17703][SQL] Add unnamed version of addReferenceObj for minor objects.
## What changes were proposed in this pull request?
There are many minor objects in references, which are extracted to the
generated class field, e.g. `errMsg` in `GetExternalRowField` or
`ValidateExternalType`, but number of fields in class was limited so we should
reduce the number.
This pr adds unnamed version of `addReferenceObj` for these minor objects
not to store the object into field but refer it from the `references` field at
the time of use.
## How was this patch tested?
Existing tests.
