Disconnect relationship with VisualUrl and VisualFactory

Disconnect relationship with VisualUrl and VisualFactory

When VisualFactory destory,
VisualFactoryCache also destroy, and TextureManager also destory.
At this time, mTextureInfoContainer clear, and TextureInfo's VisualUrl destroy.

When VisualUrl destuctor called, we call VisaulFactory::Get() and try to get TextureManager.
But We are now on VisualFactory's destroy called...

This is why image-view-encoded-image-buffer.example make Segfault.

This patch move previous VisualUrl's job
to TextureManager and ImageVisual.
