Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

In dbt-labs/dbt-core#12030 we're adding the concept of volatility to functions. In adapters we should ensure that:

• If a volatility is specified for a function, then the create function statement run against the data warehouse uses the appropriate volatility keyword
• If volatility is None for a function, then no volatility keyword is used in the create function statement run against the data warehouse.
