When PSI declaration comes from the library with classfiles,
its `moduleInfo` is represented by `LibrarySourceInfo` class.
In this case we have to resort to other ways of looking for
corresponding FIR declaration
It is easy to do for classes (by `classId`) and for the properties
(by `classId` of the containing class and property's name)
It is harder for callables, so we use
`KtDeclarationAndFirDeclarationEqualityChecker` to do that
