- Remove `Scope.prototype.traverse`, `Scope#parentBlock` and `Scope#hub` ([#16705](https://github.com/babel/babel/pull/16705))

__Migration__: Use `scope.path` methods and properties instead:
```diff
--- scope.traverse(scopeRootNode, visitor, state)
+++ scope.path.traverse(visitor, state)

--- scope.parentBlock
+++ scope.path.parent

--- scope.hub
+++ scope.path.hub
```

- Remove `Scope.prototype.getAllBindingsOfKind` and `Scope.prototype.toArray`

These methods have been removed as they are not used anymore in our code base.

__Migration__: You can copy&paste them from Babel 7's source to your plugin.

__Migration__: Adapt to the new behaviour. You can use `NodePath#shouldSkip` to check whether a NodePath has been skipped before calling `NodePath#requeue()`.

__Migration__: These methods are meant to be private so there is no real migration approach. But if your plugin / build is broken by this change, feel free to open an issue and tell us how you use these methods and we can see what we can do after Babel 8 is released.
