Fix wxSpinCtrl best size calculation for GTK+ 3

Browse Source 
Don't hard code the width of spin buttons in wxGTK, this more or less worked
for GTK+ 2 (at least with the default theme, it was perfectly possible that it
also didn't work with some other ones), but not at all with GTK+ 3 where the
buttons are much wider than the hardcoded value.

Instead, do the same thing as wxSpinButton wxGTK implementation already does
and force the GTK+ widget to compute its preferred size as we need it, i.e.
without taking the text width into account, by forcing the width of the text
entry to 0.

Notice that for GTK+ 3.12+ we also need to set the max width to 0 as well to
prevent the entry from making itself big enough for that many characters,
see #17051.
