When a repo mapping manifest is available in runfiles, it is parsed and used to map apparent repository names to canonical ones in paths passed to Rlocation. The current repository, which is required to know which part of the mapping to apply, is either determined using `CurrentRepository` or can be passed in explicitly. With this commit, runfiles lookups should succeed with Bzlmod without code changes.
