feat(amazon q transform): Chat Invocation #4540

Problem
Rather than using assorted and disparate IDE UX features to drive the Q Transformation process, we would like to have the customer be able to do the majority of it through Q Chat.

Solution
This PR moves the logic governing the /transform quick action to its own chat handler, which then takes user input to determine which module to transform and tracks the job submission status.
