[SPARK-3911] [SQL] HiveSimpleUdf can not be optimized in constant folding
```
explain extended select cos(null) from src limit 1;
```
outputs:
```
Project [HiveSimpleUdf#org.apache.hadoop.hive.ql.udf.UDFCos(null) AS c_0#5]
MetastoreRelation default, src, None
== Optimized Logical Plan ==
Limit 1
Project [HiveSimpleUdf#org.apache.hadoop.hive.ql.udf.UDFCos(null) AS c_0#5]
MetastoreRelation default, src, None
== Physical Plan ==
Limit 1
Project [HiveSimpleUdf#org.apache.hadoop.hive.ql.udf.UDFCos(null) AS c_0#5]
HiveTableScan [], (MetastoreRelation default, src, None), None
```
After patching this PR it outputs
```
== Parsed Logical Plan ==
Limit 1
Project ['cos(null) AS c_0#0]
UnresolvedRelation None, src, None
== Analyzed Logical Plan ==
Limit 1
Project [HiveSimpleUdf#org.apache.hadoop.hive.ql.udf.UDFCos(null) AS c_0#0]
MetastoreRelation default, src, None
== Optimized Logical Plan ==
Limit 1
Project [null AS c_0#0]
MetastoreRelation default, src, None
== Physical Plan ==
Limit 1
Project [null AS c_0#0]
HiveTableScan [], (MetastoreRelation default, src, None), None
```
