We could also add `NOT_NULL_CONSTRAINT_VIOLATION.STRUCT_FIELD` for
non-nullable StructField, but this case now it's buried under
`DATATYPE_MISMATCH.CAST_WITHOUT_SUGGESTION` as below:
```sql
spark-sql> SELECT CAST(named_struct('a', null) AS STRUCT<a int not null>);
[DATATYPE_MISMATCH.CAST_WITHOUT_SUGGESTION] Cannot resolve "named_struct(a,
NULL)" due to data type mismatch: cannot cast "STRUCT<a: VOID>" to "STRUCT<a:
INT>".; line 1 pos 7;
'Project [unresolvedalias(cast(named_struct(a, null) as struct<a:int>),
None)]
```
Let me migrate this case in separate ticket to facilitate review since the
change would requires a non-trivial amount of code modifications.
