fix(render): move new textures rendering to new package

Old textures rendering are kept in api/objects for backward compatibility.
The old textures rendering does not handle glow textures or independant
inventory tessellation. The old textures will only work with the old
GT_Renderer_Block class

New textures rendering with own tessellation in inventory and handling
of glow emisssive textures are moved to the api/render package. These must
not be used with the Old GT_Renderer_Block class or
it will crash with: Already Tessellating Exception from the Tessellator class
