[clangd] If an undocumented definition exists, don't accept documentation from other forward decls.

Summary:
This fixes cases like:
  foo.h
    class Undocumented{}
  bar.h
    // break an include cycle. we should refactor this!
    class Undocumented;
Where the comment doesn't describe the class.

Note that a forward decl that is *visible to the definition* will still have
its doc comment used, by SymbolCollector: Merge isn't involved here.
