If the delegated property operators involved are inline, and delegated property metadata parameter is not used (which is often the case, e.g., 'lazy'), we can skip those properties in metadata generation. NOT implemented: special case when only 'kProperty.name' is used by the corresponding delegated property operators. Also a sneak fix for KT-34060.
