[Qt] Use the shared HistoryItem serialization for QWebHistory

https://bugs.webkit.org/show_bug.cgi?id=106671

Reviewed by Allan Sandfeld Jensen.

Source/WebCore:

This allows a few things missing from the previous serialization code
to function while using commonly maintained code:
- The itemSequenceNumber and documentSequenceNumber that were needed
  to properly restore same-document navigations
- The form data
- The navigation hierarchy mapping the frame tree

Source/WebKit/qt:

Bump the serialization version and change the code to abort the
restore of a previous stream version rather than trying to keep the
support of restoring previous versions. This is mainly to simplify
things given that HistoryItem itself aborts in that case.

* tests/qwebhistory/tst_qwebhistory.cpp:
(tst_QWebHistory::serialize_2): Modify the test to cover same-document navigations.
(tst_QWebHistory::restoreIncompatibleVersion1): Add a previous version
hard-coded stream to verify that the deserialization doesn't hang or
crash.
