tools/resolve_btfids: Refactor set sorting with types from btf_ids.h
Instead of using magic offsets to access BTF ID set data, leverage types from btf_ids.h (btf_id_set and btf_id_set8) which define the actual layout of the data. Thanks to this change, set sorting should also continue working if the layout changes. This requires to sync the definition of 'struct btf_id_set8' from include/linux/btf_ids.h to tools/include/linux/btf_ids.h. We don't sync the rest of the file at the moment, b/c that would require to also sync multiple dependent headers and we don't need any other defs from btf_ids.h.
