RFR: 8304687: Move add_to_hierarchy

[Coleen Phillimore]

Moved SystemDictionary::add_to_hierarchy to InstanceKlass::add_to_hierarchy where it more logically belongs and next to other functions that also care about dependencies.
Tested with tier1-4, and tier1 on linux,windows,macos to check header file changes.
