[SPARK-17016][SQL] Improve group-by/order-by ordinal error reporting
## What changes were proposed in this pull request?
This patch improves error handling for group-by/order-by ordinals:
1. Report error position in more places.
2. Throw AnalysisException instead of UnresolvedException, which is an
internal exception not meant for end-users.
3. Made error messages more consistent.
## How was this patch tested?
This is tested in SPARK-17015 but I'm submitting this part in isolation so
it is easier to back port into branch-2.0.
