Add expandable tool calls component

[rebeccaalpert]

Add new card similar to feedback/sources card that allows user to take action when LLM suggests a tool call. Would require tests and demo in Bot Messages section on the Messages page. Spread props down to any PatternFly components we use as children so consumers can do whatever they so desire.
