[I] [C++] Neon not enabled on Windows ARM64 [arrow]

pitrou opened a new issue, #49882:
URL: https://github.com/apache/arrow/issues/49882

   ### Describe the enhancement requested
   
   It seems that, currently, Neon is not enabled at all on Windows ARM64 builds:
   https://github.com/apache/arrow/actions/runs/25043252865/job/73351674163?pr=49756#step:11:377
   
   The reason was lack of xsimd support. However, xsimd [now supports](https://github.com/xtensor-stack/xsimd/commit/1c6c7f0ac578c9aea1d8d08afce7d8ee9587491f) Windows ARM64 on its main branch.
   
   So we can probably re-enable Neon on Windows once a new xsimd version is released.
   
   ### Component(s)
   
   C++

   I am also running into this on the R side. PR to update xsimd: https://github.com/apache/arrow/pull/52023
