If the id was previously registered with register_id when building this LintLevelMap this returns the corresponding lint level and source of the lint level for the lint provided.

If the id was not previously registered, returns None. If None is returned then the parent of id should be acquired and this function should be called again.

Returns if this id has lint level information.
