Same as the preceding commits, storing the "core.warnAmbiguousRefs" value globally is misdesigned as this setting may be set per repository. Move the logic into the repo-settings subsystem. The usual pattern here is that users are expected to call `prepare_repo_settings()` before they access the settings themselves. This seems somewhat fragile though, as it is easy to miss and leads to somewhat ugly code patterns at the call sites. Instead, introduce a new function that encapsulates this logic for us. This also allows us to change how exactly the lazy initialization works in the future, e.g. by only partially initializing values as requested by the caller.
