Improves performance by avoiding copying some of the columns during

<!--

the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
## What changes are included in this PR?
Adds a projection to FilterExec similarly to
https://github.com/apache/datafusion/pull/9236 for HashJoinExec. It also
resuses a lot of the logic from that PR to implement the pushdown.
<!--
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.

## Are these changes tested?
Existing tests.
<!--
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)?
-->
## Are there any user-facing changes?
Yes, projections can now be pushed into the FilterExec.
<!--
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.
