Implement serialization of tensor descriptors and use it in primitives.

It may worth extending the common tensor descriptor abstraction to support serialization (with custom prefix). This would allow for uniform serialization of TDs in different primitives + for removal of duplicated code. Currently each primitive uses its own code for serialization of TDs.

The exception is convolutions, where I would like to keep the current implementation of serialization of TDs for the sake of backward compatibility. When/if we decide to drop bwd compatibility of conv databases, we can switch to common machinery.
