If we have an index contributor depending on the search engine adapter, it will result in a soft circular dependency. Per LPS-80843, these cycles are to be avoided. However, search engine adapters not only are used to create synonym indexes, they are likely to be used a lot in index contributors. So we need a way to allow search engine adapters as dependencies in index contributors without causing a dependency loop.
