Mike Kaganski 1ac5353bbb Use weak reference to SfxObjectShell in SfxEventHint to avoid use-after-free
The events may be processed after the shell has been destroyed. This is
happening reliably after commit e2bfc34d14
(Reimplement OleComponentNative_Impl to use IGlobalInterfaceTable,
2024-03-11) when controlling LibreOffice from external Java scripts; but
obviously, it could happen before as well.

Now SotObject inherits from cppu::OWeakObject, instead of SvRefBase.
