Removing need for asynchronous thread to execute ResourceManager finalizers (#6335) 
While Enso runs single-threaded, its `ResourceManager` required additional asynchronous thread to execute its _"finalizers"_. What has been necessary back then is no longer needed since _GraalVM 21.1_. GraalVM now provides support for submitting `ThreadLocalAction` that gets then picked and executed via `TruffleSafepoint` locations. This PR uses such mechanism to _"inject"_ finalizer execution into already running Enso evaluation thread.

Requiring more than one thread has complicated Enso's co-existence with other Truffle language. For example Graal.js is strictly singlethreaded and used to refuse (simple) co-existence with Enso. By allowing Enso to perform all its actions in a single thread, the synergy with Graal.js becomes better.

The Enso Engine

The Enso engine is the codebase responsible for compiling and executing Enso code, as well as providing language server functionality to users of the language. It is subdivided into two major components:

  • Language Server: The Enso language service.
  • Polyglot API: The truffle-boundary safe API for communication between the language server and the runtime.
  • Runner: The command-line interface for Enso.
  • Runtime: The compiler and interpreter for Enso.
