Cleanup NodePath methods

[nicolo-ribaudo]

There are a lot of methods on NodePath that aren't really meant to be public -- it's just that we expose all the function exported by the internal files that implement the various NodePath actually-public methods.

We should go through all of them and only expose those that are actually used outside of @babel/traverse, ideally with an explicit list rather than doing

babel/packages/babel-traverse/src/path/index.ts
