IMPALA-11722: Wrong error message when unsupported complex type comes from *
expression
Adds the missing check for unsupported struct fields when SlotRef
is created from an expanded path from star expression. For example:
'select * from functional_orc_def.complextypestbl;' reports
NullPointerException instead of reporting an AnalysisException: 'Struct
containing a collection type is not allowed in the select list.'
Now the struct condition checks are placed at every callsite.
Analyze tests added for erroneous queries.

> The following query fails with a NullPointerException:
> {code:java}
> select * from functional_orc_def.complextypestbl;
> ERROR: NullPointerException: null
> {code}
> The table contains a struct, {{{}nested_struct{}}}, which is not supported
> yet because it contains collections. If the columns are listed explicitly,
> the error message is the correct one:
> {code:java}
> select id, int_array, int_array_array, int_map, int_map_array, nested_struct
> from functional_orc_def.complextypestbl;
> ERROR: AnalysisException: Struct containing a collection type is not allowed
> in the select list.{code}
> The same error message should be returned in the select * case.
