fix: Make it possible to annotate nodes

[dcyriller]

I've added a test that fails with this error:

  stack: Error: ember-template-recast could not handle the mutations of `_isElseIfBlock` on BlockStatement
    at ParseResult.print (d:\a\ember-template-recast\ember-template-recast\src\parse-result.js:993:13)

It looks impossible to annotate an else if node right now. The type of the node is BlockStatement.

This is an issue I ran into while switching to use ember-template-recast in ember-template-lint. The rule involved there is: lint-block-indentation.

I'm not quite sure in which direction to go. I see two options: 1/ refactor the visitor on ember-template-lint side to annotate the node in a different way; 2/ fix the annotation here in ember-template-recast. I would go for the second option, but may you confirm @rwjblue?

EDIT: added the error stacktrace

Ya, we should try to fix here.

I think the path forward would be to make the error (Error: ember-template-recast could not handle the mutations of _isElseIfBlock on BlockStatement) only get fired if the property exists on the AST node of that type 🤔

Thanks! It's implemented now.
