Vadim Zeitlin 716dace3d6 Make wxDataViewCtrl::Expand() expand ancestors in native ports too
Expand() called ExpandAncestors() in the generic wxDataViewCtrl implementation
but not in the native ones, resulting in observable difference in the
behaviour: for example, the wxDataViewTreeCtrl in the dataview sample appeared
initially expanded under MSW, using the generic version, but collapsed under
GTK and OSX.

Harmonize this among all ports. This also has a nice side effect of making
Expand() less horribly inefficient as it is not recursively called by
ExpandAncestors() which it itself used to call: now ExpandAncestors() only
calls DoExpand() which is a simple function that only expands the item passed
to it and does nothing else.

Closes .
