/**
* Represents a set of declarations that should have
* kotlin.native.HiddenFromObjC annotation added in their IR and descriptors.
*
* It's used by [AddHiddenFromObjCSerializationPlugin] to determine
* if there's a need to modify the declaration descriptor before it's serialized.
* This set is populated by [AddHiddenFromObjCLowering].
*
* More context:
* The reason why we need this set is due to k/native ObjCExportMapper.kt is
* using descriptors to look at the declaration annotations.
* When ObjCExportMapper.kt migrates to FIR, we will need to simply remove this interface
* and [AddHiddenFromObjCSerializationPlugin].
* Adding the annotation in IR - [AddHiddenFromObjCLowering] will likely be enough.
