The runfiles manifest entry path for a file
This is the full runfiles path of a file including its workspace name as
the first segment. We refert to it as the manifest path as it is the path
flavor that is used for in the runfiles MANIFEST file.
We must avoid using non-normalized paths (workspace/../other_workspace/path)
in order to locate entries by their key.

**RETURNS**
The runfiles manifest entry path for a file
## to_workspace_path
to_workspace_path(ctx, file)

repository name if the file is from an external repository.
