Add support for Spark SQL dialect #21653
Description
Is your feature request related to a problem or challenge?
I would like to be execute Spark SQL against a DataFusion context that has Spark-compatible expressions registered from the datafusion-spark crate. This would open up opportunities for a better test approach in datafusion-spark with slt files using Spark SQL syntax.
