SNOW-2040837: Add tool calling support to `complete()`

[cpsievert]

It doesn't seem currently possible to make use of tool calling as described here

https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-llm-rest-api#tools-configuration

Thanks for reaching out -- this will be coming in the next release.

It's not clear to me from the changelog or the source code how to include tool calls. Is there any documentation you can point me to?
