After https://crrev.com/2390861 we started to use source texture for all operations on original context. SharedImageBacking are ref-counted by their representation, but the source_texture was deleted when client deletes shared image (i.e when FactoryRepresentation is deleted). This is problematic as shared image could be deleted before raster finished. This CL adds ref-counted wrapper to source texture to keep it alive until last representation on original context and thread is alive.
