Unknown query type SynonymQuery in ComplexPhraseQueryParser for boolean clauses [LUCENE-9377]

Follow up for #8746.

ComplexPhraseQueryParser fails with

```java
Unknown query type:org.apache.lucene.search.SynonymQuery
```

exception on queries like name: "(dog cat) something" if dog expands by SynonymFilter.

For now parser converts to BooleanQuery only top-level SynonymQueries, but not the nested ones.

Looks like it can be fixed by simple conversion in BQ clauses handling loop similar to #8746.

Start in ComplexPhraseQueryParser and inspect its BooleanQuery clauses handling loop, comparing the nested handling with the top-level SynonymQuery conversion described in the issue and #8746. Reproduce the query name: "(dog cat) something" with dog expanded by SynonymFilter, then verify that nested SynonymQuery clauses no longer produce the unknown-query-type exception.
