Use `datafusion-spark` version of `date_add` and `date_sub`

[andygrove]

What is the problem the feature request solves?

Once Comet is using a version of DataFusion that includes apache/datafusion#17024, we should consider removing Comet's implementation of date_add and date_sub and use the version from datafusion-spark instead.

We should run benchmarks first to ensure that there is no performance regression.
