Amortize the startup cost of some components (#10451) 
Building Engine, Context, ApplicationConfig and Ydoc was a adding a rather large delay during the initial startup step as all of those were blocking operations.
Moving all of those to the resource initialization step hopes to amortize some of that cost since it can be done in parallel. Had to add a `ComponentSupervisor` (open for a different name suggestion) to ensure that such delayed components are properly closed on shutdown.

# Important Notes
Adding Ydoc has added a visible delay during startup. I'm hoping that we can amortize some of that with this PR:

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.
