Generator: Detect Recursion / Mutual Recursion

[amilner42]

It would be nice if the generator could detect this:

interface x {
    propertyName: x
}

And turn it into the appropriate schema:

const xSchema = {
    name: "xSchema",
    objectProperties: {
        propertyName: { referenceName: "xSchema" },
        undefinedAllowed: true
    }
}

The same applies to mutual recursion detection, but in that case the generator will have to use withContext as well.
