make mir::ProjectionStore-impls pub-accessible

When using RA as a crate the `mir::Place` `projection` is accessible, however there is no way to translate the `ProjectionId` to a `&[PlaceElem]`, as the `ProjectionId::lookup` is private.

Personally, I would only need the `ProjectionId::lookup`-fn to be `pub`, but I don't see any reason why the others should be kept private.. am I missing something `@HKalbasi` ?
