localrepo: provide workingctx by integer revision
This allows us to use the integer representation in revset. None doesn't
work well while computing revset because revset heavily depends on and
optimized for integer revisions.
Still repo[wdirrev].rev() is None, which means the canonical form of the
working-directory revision is None.
This patch doesn't add the case for the wdirid because we can't handle short
and ambiguous identifiers here. Perhaps, the wdirid will have to be handled
in the changelog layer.
