Debugger: Work on WatchModel performance

Browse Source 
Don't instantiate repeating boilerplate item data in some
cases (such as large arrays).

This makes it necessary to access parent WatchItems in
a lot more cases than before and needs another separation of
WatchItem/WatchModel code to keep the dumper autotests
in a functional state.

For a plain std::vector<int> with 1 mio items this reduces
 extraction time from more than 2 minutes to about 3 seconds.
