Support Apple's MPS backend

[ClaudiaComito]

Since version 1.12, PyTorch supports GPU acceleration via Apple's Metal Performance Shaders (MPS) backend. https://pytorch.org/blog/introducing-accelerated-pytorch-training-on-mac/

Feature functionality device="gpu" should be a valid argument for ht.factories if the MPS backend is available for torch versions >= 1.12.

Ongoing research on branch features/1053-support-Apple-silicon-GPUs, will document here.

First few tests (PyTorch 1.13):

• only single precision supported
• multi-GPU setup unclear
• PyTorch support does not cover all operations
