Improve performance of SupplementaryResult + Modify the height of RowDltrUnits when UnitConverter is in Landscape (#249)

Browse Source 
* Modify the height of RowDltrUnits when UnitConverter  is in LandscapeLayout mode

* clean

* Use the same layout than the existing one while fixing the issue

* Refactor SupplementaryItemsControl to improve performance, not rely on parents and not force the parent element to be HorizonAlignment="stretch"

* take feedback into account

* add HorizontalNoOverflowStackPanel to vcproj.filters

* format conditionals

* replace max by std::max
