Use high quality in wxBitmap::Rescale()

Browse Source 
This function is currently used for relatively small icons in
wxArtProvider and wxSearchCtrl, so it shouldn't be a problem to use
wxIMAGE_QUALITY_HIGH from performance point of view and if it ever does
become a problem, the application could easily use wxImage::Rescale()
with a different option directly instead.
