cool#9992 lok doc sign: async DocumentDigitalSignatures::signDocumentContent()

Currently SfxObjectShell::CheckIsReadonly() has a hack for the LOK case
to show the signatures dialog read-only, as only that is async.

The next step is to make
DocumentDigitalSignatures::signDocumentContent() async, but passing an
std::function via the UNO API is tricky.

Notice how DocumentDigitalSignatures in xmlsecurity/ also implements
sfx2::DigitalSignatures, add a new SignDocumentContentAsync() there and
adapt all uses of signDocumentContent() to go with that instead.

This requires introducing some lambdas for code after
signDocumentContent() in general and for ODF/OOXML specific code in
particular, to avoid code duplication.
