Question about current state of vectorized paths for Log/Pow/Cbrt/RootN in System.Numerics.Tensors

[alexcovington]

I saw a note saying the vectorized paths for Log/Pow/Cbrt/RootN in System.Numerics.Tensors were disabled because of a bug. I looked through open issues, but I couldn't find any mention of a resolution for the bugs in the vectorized path. Wondering if a resolution is planned for .NET 10.0?

A robust vectorized implementation would be welcome. There are a bunch of TensorPrimitives methods that are still not vectorized, including these. #97193 tracks that.

@alexcovington Worth noting in many cases we're using https://github.com/amd/aocl-libm-ose and simply haven't ported these over yet.

If the AOCL LIBM has an existing algorithm that is the most preferred; otherwise we'd need to spend the time rolling our own algorithm.
