vcl: separate ImplImageTree - ImageTree singleton and public iface

ImplImageTree was used outside of VCL which is not consistent with
the name and the header also contains a lot of implementation
detail. This separates the implementation to ImplImageTree and
the public interface and singleton to ImageTree only.
