Thanks for opening a pull request! ### Rationale for this change Lot of linux systems ship arrow with SSE4.2, but the AVX2 instructions are quite available. For byte stream split, they are faster than SSE4.2. ### What changes are included in this PR? - Make the xsimd functions refactored in #46789 to make them arch independent. - Use dynamic dispatch to AVX2 at runtime if available (it was considered that builds without SSE4.2 or Neon at compile time were not so popular to add them to the dynamic dispatch). ### Are these changes tested? Yes, the exisiting tests already cover the code. ### Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
