Removing dependencies to speed up startup (#10249) 
Reducing the number of dependencies. Explicit `cats` are almost gone (present in `cli`). `enumeration` is completely gone.  `cats` is also still included implicitly via `io.circe` but that's a different kind of beast.
Also, really removed `jackson` from dependencies by fixing the dependency on `http-test-helper`.

# Important Notes
In a number of places importing all cats implicits could be simply replaced with a single or two method calls. Not to mention that this will reduce compilation times due to reduced implicit search space.

One example of how the changes affect performance (not only startup):

Also appears to be gone.

This PR is by no means finished. The purge will continue in follow up PRs.

Enso Language Server

The Enso Language Server is responsibile for providing a remote-communication protocol for the runtime, exposing many of its features to the users. In addition it provides the backing service for much of the IDE functionality associated with the language. It encompasses the following functionality:

  • 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.
