* use_resource API misunderstood. It is not additive. Several usages must be bit-ORed together.
* The seeding was incorrect and used the address instead of the value of the passed in seed.
* Add a check that likely exhibits failure to update the seed between generation of random tensors.
* Buffer overrun, the length given to the std::ptr::copy call was in bytes, and not 32-bit units.
* By default seed the RNG with a time-based value, so that different runs may produce different output, just like the CPU engine.
Use device.set_seed if determinism is warranted.
* Revert "By default seed the RNG with a time-based value, so that different runs may produce different output, just like the CPU engine. Use device.set_seed if determinism is warranted."

* The Metal random kernel failed to set element N/2 of tensors with N elements, N being even. The reason was that all threads but thread 0 all created 2 random samples, but thread 0 only one, i.e. an odd number. In order to produce an even number of samples, the early termination of thread 0 should only everr occur for odd sized tensors.
* Add a test catching any deterministic tensor element in rand and randn output.
