tdf#114441 Convert sal_uLong to sal_uInt32 in TreeControlPeer

We are talking about a tree list in a gui which logically will not exceed sal_uInt32
They also must be unsigned integers because they represent counts & positions

changes are done to these variables:
- nPos (node position)
In all base classes you will found that all functions deal with and return sal_int32 concerning it
- nChild (node child)
It is assigned to TREELIST_APPEND which is MAX for sal_uInt32 and it is considered like that in all other functions
- nSelectionCount
all functions that deal with it (like GetSelectionCount()) returns sal_uInt32
