Send server contextualization to Copilot extension (#24230)

* Send server contextualization to Copilot extension

* Keep context in editor input

* Remove unnecessary server context and extension service

* Send context when connecting from open editor

* Remove contextualization complete event

* Contextualize editor after connection success

* Minor clean up

* Remove nested then and use async/await

* Create helper function

* Remove unneeded async and add comment

* Encapsulate all context logic in service

* Use void operator to fix floating promise

* Correct return comment
