Change the way the NonClientView handles forcing the native frame for popups/app windows.

Rather than carrying state in a force_native_frame_ member it uses a virtual method AlwaysUseNativeFrame analogous to AlwaysUseCustomFrame. This makes me a little happier.

BUG=none
TEST=On a vista capable system, test that when a theme is installed, popups and app frames are rendered with the native frame. Test that constrained windows (e.g. HTTP basic auth) are rendered with the custom frame. Without a theme installed, test that all windows have a native frame except constrained windows. With Vista Basic system setting, verify that all windows have a custom frame, including constrained windows.
