Attempt to address #87780 and #87785

It looks like pybind11_PREFER_third_party=OFF was changed to USE_SYSTEM_PYBIND11=ON - pytorch/pytorch#58951

[ankane]

It looks like the torchvision test failed due to pytorch/vision#4375, which requires PyTorch to download the model manually. I've updated the test to check ops are registered.

[ankane]

It looks like LibTorch is ignoring the USE_SYSTEM_PYBIND11 option. Created an issue upstream: pytorch/pytorch#67974

Edit: USE_SYSTEM_BIND11 works (but appears to be a typo), so we could use that temporarily.

We could pass both. CMake will ignore unrecognised options anyway. Has the typo been reported upstream?

[ankane]

Sounds good, added both for now (with a comment), and the typo is mentioned in the upstream issue.

It looks like the failures on 11 were due to an issue with brew test-bot --only-setup.
