## What changes were proposed in this pull request? This pr sorted output attributes on their name and exprId in `AttributeSet.toSeq` to make the order consistent. If the order is different, spark possibly generates different code and then misses cache in `CodeGenerator`, e.g., `GenerateColumnAccessor` generates code depending on an input attribute order. ## How was this patch tested? Added tests in `AttributeSetSuite` and manually checked if the cache worked well in the given query of the JIRA.
