Add ARM64 release builds (#2159)

Creates a build_linux_arm64 job that builds the release on an arm64 self-hosted runner.
Drop Python 3.10 support
Pass  TM_TORCH_VERSION to choose the Stable PyTorch version (since arm64 doesn't have nightly builds)

Borrows nightly / stable Pytorch switch from the WIP
