Armin Le Grand (collabora) 5519a3d407 Correct StyleSheet handling when cloning to different Model II 
Until now the 'local' StyleSheet got set, but that may
not be the same as the original. It was/gets identified just
by searching by name and type, not comparing content.

What to do? We could...

(a) the Style-Friendly way:
 - check if StyleSheet is identical
  - if not, create a new in-between StyleSheet hosting missing Items
  - if yes, use, done.

(b) the pragmatic/practical way:
 - Just hard-attribute the Items that are detected as different
   similar to what BurnInStyleSheetAttributes does/did, but only
   for a view differing Items

(b) is the most simple for now, but will lead to more hard
attributes. The other possibilities will be better in the
long term. For now, I will use (b).

Note that there are more cases in that VERY complex and grown
stuff emerging from SdDrawDocument::PasteBookmarkAsPage. More
things will need to be fixed, see this as a 1st step.

Needed to adapt postProcessAfterCloneToDifferentModel due to
UT testTdf96206 failing, see comment there for details.

That 1st implementation showed weaknesses with those Items
critical and only on MasterPages, so decided to give up on
that and implement ContentCompare to SdPage::Equals. That
was easier than thought: No parameter needed, only used by
InsertBookmarkAsPage_FindDuplicateLayouts::operator(). Thus,
SdPage::Equals needs no change, just SdrObject::Equals.

Due to still problems with Items corrected in Objects on
MasterPages I will for now exclude this.

Could now isolate remaining problems, these are defaults
and/or PresObj things on MasterPages. Important is that I can
completely correct all Items for all Objects in
postProcessAfterCloneToDifferentModel. I can react to these
false-positives in the ContentCompare in SdrObject::Equals.
