Instrument tool calls responses

[RulaKhaled]

Client tool calls are only executable on the user's local system so we cannot auto instrument them, but we can emit attributes of calls such as gen_ai.tool.id and gen_ai.tool,name.

Anthropic also supports server tools, these are executable in Claude system, we probably can't do much here, but look into it.
