Disable stretchable spaces in multi-row toolbars in wxMSW.

Browse Source 
Stretchable separators simply don't work correctly when the space they are
supposed to stretch onto is distributed across several different toolbar rows
or columns, so just disable them for multi-row (or column, for vertical
toolbars) case.

See #13579.
