The CI tests are failing on arm64 linux because torch_sprarse has a dependency on torch_scatter wheel which is not yet available. This PR depends on rusty1s/pytorch_scatter#483 that's adding the torch scatter wheel support for arm64.

Hi @rusty1s , thanks for merging the scatter, cluster and spline_conv PRs.
Please let's know what the next step is to publish those wheels for arm64 linux platform. for example, here: https://data.pyg.org/whl/torch-2.6.0%2Bcpu.html
so that torch-sparse CI tests will pass on arm64 linux, right now it's failing due to the missing wheels for cluster.

I build them when PyTorch 2.7 is available (should happen next week).

Hi @rusty1s , please let's know if you are looking for publishing the aarch64 wheels with PyTorch 2.7, happy to collaborate.
