Make Invoke edges bi-directional

[KuechA]

Currently, we can use the Invoke edge to reach a FunctionDeclaration from a CallExpression. However, it is handy to have an opportunity to follow the edges in the opposite way too (e.g. invokedBy or callSite). We can probably implement this with the edges magic quite easily

Not possible, since the mirror collection only supports mirroring between same node types and we would need to mirror between a CallExpression and a FunctionDeclaration :(

Ok It is possible, but the unwrapping is not really possible.

Ok unwrapping is also possible with some (tolerable) pain
