RFR: 8356390: Rename ResolvedIndyEntry::set_flags to set_has_appendix [v5]

[Johan Sjölen]

> The `set_flags` function really only sets whether it has an appendix or not, and there's a separate `set_resolution_failed` method just below that also alters the flag. Just rename this to `set_has_appendix`
