Prebuilt binaries of torch.audio for aarch64 cuda

[chulkilee]

🚀 The feature

torch.audio provides prebuilt binaries for aarch64 + cuda on linux

Motivation, pitch

pytorch now provides aarch64 cuda prebuilt binaries in 2.4.0 (pytorch/pytorch#134117) but currently torch.audio doesn't provide corresponding prebuilt binaries. It makes very hard to adopt torch on aarch64 + cuda environment, which is often much cheaper in cloud providers.

Alternatives

Build torch.audio from source, which is not ideal for users of this library since it requires lots of works.

Additional context

Nightly binaries are already available for ARM+CUDA. The PyTorch 2.4.0 release only added the torch wheels without torchvision and torchaudio as the latter two builds were created late in the release cycle and thus to avoid last minute churn.
