Summary:
As part of Project Nova, we are consolidating CI/CD workflows and infra, making them reusable across PyTorch ecosystem libraries. https://github.com/pytorch/test-infra/pull/460 introduces a general-purpose reusable workflow to build linux wheels for python libraries. This PR introduces a caller workflow that triggers the reusable workflow. Details around modular env setup, passing input args across workflows, etc. are still being worked out.

Using reusable workflow defined in https://github.com/pytorch/test-infra/pull/506
