It's very slow and leads to performance problems (see KT-58125)
Instead, we do the following:
- For a fully resolved type qualifier, when we want to resolve its part,
we are looking for the corresponding symbol by traversing nested classes
bottom up.
- For an error qualifier, we are trying to resolve the maximum possible
qualifier in the types transformer where all the type scopes are
already available.
