export startCompletionEffect and closeCompletionEffect

[BrianHung]

Trying to programmatically open the autocompletion menu when CodeMirror is empty and focused, as opposed to requiring a Ctrl+Space.

Would need to have state effects exported if I want to use https://codemirror.net/docs/ref/#state.EditorState^transactionExtender.

Work-around right now is using updateListener, and calling startCompletion.

EditorView.updateListener.of(
  ({ docChanged, view, state }) => {
    const shouldOpen = (docChanged || view.hasFocus) && !completionStatus(state);
    if (!state.doc.length && shouldOpen) {
      startCompletion(view);
    }
  }
)

This works but requires an additional check that completionState isn't already open to prevent an infinite loop of updates.

But I view this as more similar to the auto language example here https://codemirror.net/examples/config/

I think your workaround is decent enough. Exporting these doesn't seem worth it without a more compelling use case.
