Internals: using ItemAdd() consistently for internal items: windows & tables resize grips/borders, ScrollbarEx().

Browse Source 
This put an extra flag check in ItemAdd() but essentially reduce inconsistency with windows decorations not using this. Useful for debugging.
It however buries the info/blurs the line about what it means to not use ItemAdd() since they are now doing it much less.
