## Rationale for this change
<!--

the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your

-->
DataFusion Comet is currently maintaining a fork of FilterExec with a small
modificiation to change the way that filtered batches are created. We have a
requirement that we do not want FilterExec to pass through input batches in the
case where the predicate evaluates to true for all rows in a batch (due to some
array re-use in our scan).
We would like to make the DataFusion implementation of FilterExec
customizable to meet our needs.
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Add a new `FilterKernel` enum so that we can choose how filtered batches are
created.
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
I did not add tests yet. I wanted to get some feedback on approach first.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
