telemetry(chat): differentiate chat vs agenticChat (aws#7039)

## Problem
- differentiate `Chat` vs `AgenticChat` for cwsprChatConversationType
- stop button functionality changed so event is being incorrectly
emitted

## Solution
- emit `AgenticChat` for cwsprChatConversationType
- correctly emit event when user clicks stop button
- aws/aws-toolkit-common#1012
