Once paimon supports `SupportsRuntimeFiltering` to enable dynamic partition
pruning, spark requires that the DPP expression must have the same result (see
`sameResult` interface in `QueryPlan`) as one `BroadcastExchange` plan. Then
`sameResult` will call `BatchExecScan`'s equals method indirectly.
```
override def equals(other: Any): Boolean = other match {
case other: BatchScanExec =>
this.batch == other.batch && this.runtimeFilters ==
other.runtimeFilters
case _ =>
false
}
```
Here. this `batch` is paimon implementation of `Batch`, so we need to
override `equals` methods related to `Batch`.
