Improve shutdown logic of language server (#7801) 
* Improve shutdown logic of language server

This PR addresses problems mentioned in #7470 and #7729:
- shutting a language server explicitly will not lead to a soft shutdown
- `project/status` endpoint returns the state of the language server

`LanguageServerController` now also signed up for `ClientConnect`
messages. For it to be unambiguous, we need to carry around the port
number of the language server as a way of identifying the right one.

One can now use `project/status` to additionally determine the state of
the language server.

Also relies on a proper fix for #7765.

Language Server

The Enso Language Server is responsible for providing language services to the Enso IDE (and other clients). This mainly involves speaking the Enso protocol and orchestrating the runtime in response to this. It is responsible for:

  • Introspection Services: Giving clients the ability to observe information about their running code including values, types, profiling information, and debugging.
  • Code Execution: The ability for clients to execute arbitrary Enso code in arbitrary scopes. This can be used in conjunction with the above to provide a REPL with an integrated debugger.
  • Code Completion: Sophisticated completion functionality that refines suggestions intelligently based on context.
  • Node Management: Tracking and providing the language server's internal node representation of the Enso program.
  • Code Analysis: Analysis functionality for Enso code (e.g. find usages, jump-to-definition, and so on).
  • Refactoring: Refactoring functionality for Enso code (e.g. rename, move, extract, and so on).
  • Type Interactions: Features for type-driven-development that allow users to interact with the types of their programs.

This folder contains all documentation pertaining to the Language Server, which is broken up as follows:

The protocol messages are broken up into documents as follows:
