We now need to convert from type ids to type names while adding a diff
message, since types don't have type names as references anymore.
Bug: 71486971
Test: tests/test.py test updation CL; all tests pass.
Test: tests/gen_all.py; manually diff between libcpp_gold.so.lsdump and
libcpp_gold_member_diff.so.lsdump, diff is visually the same as
before.
Test: build android source tree for aosp_arm64_ab; create reference
dumps; rebuild; confirm no errors or warnings.
