Some functions were already a stub and only aborted on calling them.
The *Package* functions were added in commit
c9ed2f359a (INTEGRATION: CWS xmlsec08
(1.4.24); FILE MERGED 2005/02/22 13:07:19 mt 1.4.24.1: #i36682# Accept
separate Stream for signatures..., 2005-03-10), but it seems nobody
called them.
This also means that DocumentSignatureMode is now never set to
DocumentSignatureMode::Package, so remove that as well.
It seems to be unlikely that this non-published service was used by
3rd-party code, since it was specific to the needs of sfx2/ code, not
generic functionality that could be useful in other contexts.
