perf: Avoid redundant copying of arrays in scan->filter->join

[andygrove]

Which issue does this PR close?

Closes #757

Rationale for this change

Improve performance of joins by removing some redundant copying of arrays for join inputs.

What changes are included in this PR?

This PR adds a new CometFilterExec which is a copy of DataFusion's FilterExec with one small change to ensure that input arrays are never emitted without copying:

// BEGIN HACK: this is the only modification to the DataFusion version
// we ensure that we never return the original arrays
let filtered_batch = if filtered_batch.num_rows() == batch.num_rows() {
    RecordBatch::try_new(
        filtered_batch.schema(),
        filtered_batch
            .columns()
            .iter()
            .map(|array| copy_array(array))
            .collect(),
    )?
} else {
    filtered_batch
};
// END HACK

In planner.rs we have this check for join inputs:

let left = if can_reuse_input_batch(&left) {
    Arc::new(CopyExec::new(left))
} else {
    left
};

Because can_reuse_input_batch returns false for CometFilterExec, we are longer creating the CopyExec.

How are these changes tested?
