30cb6ac5 - Introduce `mlc` device (ML Compute device) to PyTorch's device list (#50634)

Introduce `mlc` device (ML Compute device) to PyTorch's device list (#50634) Summary: Apple recently announced ML Compute, a new framework available in macOS Big Sur, which enables users to accelerate the training of neural networks on Mac hardware. This PR is the first on a series of PRs that will enable the integration with ML Compute. Most of the integration code will live on a separate subrepo named `mlc`. The integration with `mlc` (ML Compute) will be very similar to that of xla.
