Consider excluding placeholder numbered parameters when one isn't declared in the header

We show numbered placeholder parameters in APIView on methods that don't have any named parameters. I am not sure what the best behavior is here that we'd want.

Start with the APIView diff for assembly 3226949419594af785233c8289dd76ef and inspect client_options.hpp around line 62 to understand how the numbered placeholders are rendered. Clarify the expected behavior for methods without named parameters, then identify the APIView entry point and tests that cover this rendering; done means the agreed behavior is represented consistently in the review output.
