[SPARK-3345] Do correct parameters for ShuffleFileGroup

In the method `newFileGroup` of class `FileShuffleBlockManager`, the parameters for creating new `ShuffleFileGroup` object is in wrong order.

Because in current codes, the parameters `shuffleId` and `fileId` are not used. So it doesn't cause problem now. However it should be corrected for readability and avoid future problem.

[SPARK-2973][SQL] Lightweight SQL commands without distributed jobs when calling .collect()

By overriding `executeCollect()` in physical plan classes of all commands, we can avoid to kick off a distributed job when collecting result of a SQL command, e.g. `sql("SET").collect()`.

Previously, `Command.sideEffectResult` returns a `Seq[Any]`, and the `execute()` method in sub-classes of `Command` typically convert that to a `Seq[Row]` then parallelize it to an RDD. Now with this PR, `sideEffectResult` is required to return a `Seq[Row]` directly, so that `executeCollect()` can directly leverage that and be factored to the `Command` parent class.

[SPARK-2961][SQL] Use statistics to prune batches within cached partitions

This PR is based on #1883 authored by marmbrus. Key differences:

1. Batch pruning instead of partition pruning

   When #1883 was authored, batched column buffer building (#1880) hadn't been introduced. This PR combines these two and provide partition batch level pruning, which leads to smaller memory footprints and can generally skip more elements. The cost is that the pruning predicates are evaluated more frequently (partition number multiplies batch number per partition).

1. More filters are supported

   Filter predicates consist of `=`, `<`, `<=`, `>`, `>=` and their conjunctions and disjunctions are supported.
