tests/qapi-schema: Demonstrate feature and enum doc comment bugs

Add negative tests doc-bad-enum-member and doc-bad-feature to cover
documentation for nonexistent enum members and features, and test
doc-undoc-feature to cover features lacking documentation.  None of
them works.  To be fixed later in this series.
