KT-14513 Don't generate delegated property metadata when unused

Browse Source 
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.
