This allows the program to get at the singleton component context for the currently running component. The component context can be meaningfully instantiated only once; and since dart doesn't have a predefined way to wire platform-specific values into platform-specific code, we instantiate a singleton here, so all code that is interested can use it. The users of this functionality will be the dart and flutter fuchsia runners. See issue https://github.com/dart-lang/sdk/issues/41523 for details. Tested: manual compile for fuchsia, check behavior.
