Possibly missing exports from ckeditor5 package

📝 Provide a description of the new feature

What is the expected behavior of the proposed feature?

Per request on the latest release, here are the imports that are currently still part of our build with custom plugins that are not exposed in the new ckeditor5 package:

1. import {type PlaceOrOffset} from '@ckeditor/ckeditor5-engine/src/model/selection';
   Used for a custom Command in our plugin, that allows inserting some specific content "near" the selected element. This command has a constructor with a position argument to allow for easy reuse, which is typed PlaceOrOffset to match with the expected type on Model.insertObject. Alternatively I could introduce a custom similar type (maybe even more restrictive), but I'd prefer an import.
2. import {isLinkElement} from '@ckeditor/ckeditor5-link/src/utils';
   Used within a custom plugin that is very similar to the Link plugin.

Hopefully this is helpful enough and these usecases may warrant exporting them from the new package. If not, feel free to close!

Thanks! I really appreciate the feedback. We will take it into account in our discussions, and we should soon publish some thoughts about our general approach to exports.
