Unions make handling of non-trivial data 'members'... non-trivial. Since `PointerRNA` is going to become non-trivial, this commit replaces the Union storing delta, min and max values of editied RNA properties in `ui_selectcontext_apply`, into a `std::variant`. It also adds a new accessor to RNA string properties, returning a `std::string` data, and uses this type to store string properties values in `ui_selectcontext_apply`.
