dirstate: add a concept of "fallback" flags to dirstate item

The concept is defined and "used" by the flag code, but it is neither persisted
nor set anywhere yet. We currently focus on defining the semantic of the
attribute. More to come in the next changesets

Check the inline documentation for details.
