sizegroup: Use _gtk_widget_compute_size_for_orientation()

Browse Source 
With this function now available, we can do size computation in 2
ways:
(1) Compute size with size groups
(2) Compute size without size groups

And have (1) use (2) instead of setting flags on widgets. This patch
does exactly that.
