I am not sure if VC-specific function implementations, such as
`project-files', work for store project.

Even if they do or will do, I still do not think it is a good idea to
handle store projects via VC function implementations:

- Store projects need a different implementation of `project-name' than
  VC projects.
- Conceptually, store projects are not relevant to VC.  So handling
  store projects via VC-specific implementations just causes unnecessary
  confusion.

I think adding public helpers to caching in project.el is a good idea.
