[SPARK-36454][SQL] Not push down partition filter to ORCScan for DSv2

### What changes were proposed in this pull request?
not push down partition filter to `ORCScan` for DSv2

### Why are the changes needed?
Seems to me that partition filter is only used for partition pruning and shouldn't be pushed down to `ORCScan`. We don't push down partition filter to ORCScan in DSv1
```
== Physical Plan ==
*(1) Filter (isnotnull(value#19) AND NOT (value#19 = a))
+- *(1) ColumnarToRow
   +- FileScan orc [value#19,p1#20,p2#21] Batched: true, DataFilters: [isnotnull(value#19), NOT (value#19 = a)], Format: ORC, Location: InMemoryFileIndex(1 paths)[file:/private/var/folders/pt/_5f4sxy56x70dv9zpz032f0m0000gn/T/spark-c1..., PartitionFilters: [isnotnull(p1#20), isnotnull(p2#21), (p1#20 = 1), (p2#21 = 2)], PushedFilters: [IsNotNull(value), Not(EqualTo(value,a))], ReadSchema: struct<value:string>
```
Also, we don't push down partition filter for parquet in DSv2.
