Niels Lohmann f8a0990582 Document zero-member support in the macro API reference
docs/mkdocs/docs/features/arbitrary_types.md already gained a note, but
the three api/macros pages are where the parameter contract is actually
specified and they still described member as a non-empty list.

State that the list may be empty on each page, and add a note showing
what the zero-member case generates: an empty JSON object for the plain
macros, and base-type-only serialization for the derived ones. Both notes
record that the WITH_NAMES variants do not support this.
