Revert the svn_types.h change made in r40417.

The inclusion of svn_debug.h by the svn_types.h means that the debug
functionality will be available to all of our files, all the time. This
makes it much easier for our devs to use the debug facilities.

The inclusion of the private header is wrapped by SVN_DEBUG, so formal
releases will never attempt to include that header.

* subversion/include/svn_types.h:
  (): restore the inclusion of private/svn_debug.h
