Description

As discussed https://github.com/apache/arrow/pull/9108#issuecomment-755791235

We would like to pick a single SQL dialect in DataFusion to avoid what happened with Spark SQL where functions, https://spark.apache.org/docs/latest/api/sql/index.html, were added seemingly ad-hoc making their usage very difficult and no clear feature matrix available.

Using an existing dialect will also allow us to re-use the documentation (and other tools) from that dialect.
