Mark some classes as final

...namely exactly those for which fa91dd31f39a24329d288d4e1cda28db3a16af0d
"5th step to remove tools/rtti.hxx" (which is assumed the culprit in tdf#96067
"Crash on undo row inserts") had replaced exact-type checks of the form

  v->Type() == TYPE(X)

with type-or-subtype-of checks of the form

  dynamic_cast<X *>(v) != nullptr

which is only sound if X is a final class.  (Except for one case already handled
differently in 791ad3e170bcb5a2daedac77932dc9822f7f1092 "Stick to exact-type
check.")
