[SPARK-24951][SQL] Table valued functions should throw AnalysisException
## What changes were proposed in this pull request?
Previously TVF resolution could throw IllegalArgumentException if the data
type is null type. This patch replaces that exception with AnalysisException,
enriched with positional information, to improve error message reporting and to
be more consistent with rest of Spark SQL.
## How was this patch tested?
Updated the test case in table-valued-functions.sql.out, which is how I
identified this problem in the first place.
