RoundRect does not call its children's resize()

[ykami]

dojox.mobile.RoundRect is a container widget, but it does not call its children's resize(). Therefore, in the following case for example, resize() of the Chart widget is not called even when resize() of View is called expecting resize() for each descendant widget is called.

<div dojoType="View">
   <div dojoType="RoundRect">
       <div dojoType="Chart"></div>
  </div>
</div>

Also, resize() of dojox.mobile.ContentPage is not called at startup.

(In [24229]) Fixes #12623 !strict. Fixed a problem where resize() is not called under some conditions.

Added resize() to RoundRect. In addition to that, slightly modified the resize strategy. After the view transition, instead of calling view.resize(), search the view recursively for top-level resizable widgets and call resize() for each found widget. This way, even if RoundRect has no resize method, its children's resize() will be called.
