Summary: Batch get statistics of multiple partitions instead of
get one by one
Key: FLINK-25605

Currently, `PushPartitionIntoTableSourceScanRule` would fetch statistics of
matched partitions one by one.

If there are multiple matched partitions, it costs much time to waiting for get
all statistics.
We could make an improvement here to batch get statistics of multiple
partitions.
