dirstate-entry: turn dirstate tuple into a real object (like in C)

With dirstate V2, the stored information and actual format will change. This mean we need to start an a better abstraction for a dirstate entry that a tuple directly accessed.

By chance, the C code is already doing this and pretend to be a tuple. So it
should be fairly easy. We start with turning the tuple into an object, we will
slowly migrate the dirstate code to no longer use the tuple directly in later
changesets.
