Ultimately, will there be dialogs that _don't_ want this?  It seems like we want
to get to a world where DialogClientView does this by default.

If that's true, is there a reason not to initially implement there directly, and
to have this class instead as a transitionary thing?

Hmmm, probably not, actually. Moved this logic to DialogClientView and removed
this class.

+class SizedDialogClientView : public views::DialogClientView {
+ public:
+  SizedDialogClientView(views::Widget* widget,
+                        views::View* content_view,
+                        const gfx::Size& minimum_size);
+  ~SizedDialogClientView() override;
+
+  // views::DialogClientView:
+  gfx::Size GetPreferredSize() const override;
+
+ private:
+  gfx::Size minimum_size_;
+};
