LLM thinking blocks displayed in Logfire message view

[kasper-copli]

Description

It would be great, if the ThinkingPart objects were exported to logfire and displayed in the message thread - similar to how system message, user message, assistent message and tool call/returns is displayed.

It would make debugging LLM's during evaluation run easier, since one would be able to also follow the models reasoning process.
