Link widget for internal links allows to have entity reference autocomplete to make the selection of the page easier. Previously there was no way to set any settings for entity reference selection from the link field and widget, that is why the default settings were used for reference method and match options.
With this change it is now possible to select the reference method for link type field the same way as it is possible for entity reference field type. It allows, for example, to use views entity reference handler instead of default one.
In addition the link field default widget now has the same settings available that entity reference default widget, namely match_limit and match_operator.
