sw: allow viewing OLE objects in protected sections

The problem was that we don't allow even opening embedded objects in
protected sections, which means the content of multi-page embedded
objects can't even be viewed in protected sections, which probably goes
too far.

Fix this relaxing the condition in SwEditWin::MouseButtonDown() to allow
launching the OLE object on double-click, and then make sure that the
native data is not updated in SfxInPlaceClient_Impl::saveObject() and
the replacement image is not updated in
svt::EmbedEventListener_Impl::stateChanged().

This is complicated by only the Writer layout knowing if a given OLE
object is anchored in a protected frame, so pass down a callback to
sfx2/ and svtools/ to check if the OLE object is protected.

Not copying the protected bit has the benefit of behaving correctly if
the section turns into non-protected: copying would not work properly,
as SfxInPlaceClient is created on demand, so not re-created when the
protectedness of the section is changed.
