fix: see if message is apart of agentic loop

[chungjac]

• reference agenticChat branch pr: telemetry(chat): see if message is apart of agentic loop aws-toolkit-vscode#7069

Problem

• want to differentiate between a message without tool use (ex: what time is it) and a message with tool use (ex: write a docstring for my function)

Solution

• for both successful messages and messages that resulted in error, see if this message was apart of an agentic loop.
• An agentic loop is when the LLM asks to run a tool and the LLM receives the results back of running the tool.
