Record special descriptor in REFERENCE_TARGET for type alias object

If a type alias is used to reference an object (companion object) as a
qualifier, record FakeCallableDescriptorForTypeAliasObject in
REFERENCE_TARGET. This tells IDE that type alias was used in the file,
thus, if it's imported, such import isn't redundant.
REFERENCE_TARGET is used mostly by IDE and by ClassifierUsageChecker,
which we also have to update to handle qualifiers with
FakeCallableDescriptorForTypeAliasObject in REFERENCE_TARGET.

Rewrite some parts of ClassifierUsageChecker for cleaner interaction.
