Mark obsolete packages

The following contributed packages are (partially) obsolete.

org-browser-url.el
org-annotation-helper.el
  The functionality of both these packages is a subset of
  org-protocol.el, which is now part of the Emacs core
  and is recommended.

org-depend.el
  A significant fraction of the org-depend functionality
  dependence on siblings, children, and parents) is now
  built-in into the Org core.  Org-depend remains
  in the distribution as a proof-of-concept fro complex
  and remote dependencies.

org-interactive-query.el
  I believe that much of what this package was build for
  is now available with tag filtering.

These packages are now marked in org-modules as such.
