rebase: enable multidest by default

This was intended to be done by D470. But there was a minor documentation
issue. The feature is quite usable now so it gets formally documented and
enabled.

There is no behavior change for people not using the `SRC` or `ALLSRC` in
rebase destination revset.

.. feature:: Rebase with different destination per source revision

  Previously, rebase only supports one unique destination. Now ``SRC`` and
  ``ALLSRC`` can be used in rebase destination revset to precisely define
  destination per each individual source revision.

  For example, the following command could move some orphaned changesets to
  reasonable new places so they become no longer orphaned::

    hg rebase
      -r 'orphan()-obsolete()'
      -d 'max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::)'
