Vadim Zeitlin 97050e18e2 Let wxAuiToolBars with stretchable elements stretch ...

Previously, all fixed panes without a minimum size were forced to have a
proportion of 0 in wxAUI layout code, which meant that a wxAuiToolBar
with stretchable elements (typically spaces, but labels and controls
could be stretchable too) couldn't stretch unless its pane was given
some non-default minimum size, even if it was just wxSize(-1,1).

This was completely undiscoverable and not intuitive at all, so let
wxAuiToolBar stretch if it has any stretchable elements, regardless of
its pane min size instead.

This required adding wxAuiToolBar::CanStretch() and using an ugly
dynamic cast. We could probably avoid this by using some kind of
heuristic based on e.g. comparing min and best size, but this is simple
and guaranteed not to break anything else, so do it like this for now.

See #26252.

Closes #26249.
