Add ToolChoice Support for Anthropic API

[adase11]

I believe this could end up being a part of #3513, however for simplicity I'll make this ticket independent.

The feature request would be to support mapping the tool_choice parameter for the anthropic api https://docs.claude.com/en/api/messages#body-tool-choice.

I can set up a PR for this.
