Add cache dependencies via args resolvers

[mabar]

• [ ] Each args resolver should be able to provide list for metadata invalidation
• [ ] If possible, referenced constants fro other classes should result into referenced class being included too (e.g. from ArrayEnumRule)

e.g. BackedEnumRule should force structure to re-validate when class changes (may be deleted, not backed, not enum, ...)

Args resolvers are callbacks/fields/docs/modifiers
