Make stretchable spacers work in vertical toolbars too in wxMSW.

Browse Source 
Replace the old implementation of stretchable spacers based on changing the
size of the separators used as spacers as the toolbar size itself changed with
a new one, simply replacing the old separator with the new one of the correct
size, as it also works for the vertical toolbars, unlike the old approach.

Closes #13673.
