[SPARK-8283][SQL] Resolve udf_struct test failure in HiveCompatibilitySuite
This PR aimed to resolve udf_struct test failure in HiveCompatibilitySuite.
Currently, this is done by loosening CreateStruct's children type from
NamedExpression to Expression and automatically generating StructField name for
non-NamedExpression children.
The naming convention for unnamed children follows the udf's counterpart in
Hive:
`col1, col2, col3, ...`
