Enable CI on AWS T4 Metal instance (#1236)
Summary:
Enable T4 metal CI runs and fix functorch userbenchmark.
We need to fix a few places to run functorch userbenchmark:
1. in the CI workflow, we need to install the TorchBench models (later, we could optimize this to only install the models needed by userbenchmarks)
2. fix a bug in the functorch userbenchmark code ("git_version" -> "pytorch_git_version")
3. allow upload script to annotate with different CI platforms
