update for xsimd 13

[drew-parsons]

xsimd 12 was recently released. It provides significant improvements in stability on less common architectures such as armhf, and has stabilised handling of batch bools (essentially by not doing it), which is not supported by all architectures.

The batch changes need some updating in xtensor, likely related to #2733

For instance, if the current dependence on xsimd 11 is manually flipped to 12 in CMakeFiles.txt, then xtensor 0.24.7 (patched by #2735) gives the error

/build/xtensor/test/test_xoperation.cpp:372:9:   required from here
/usr/include/xsimd/types/xsimd_traits.hpp:71:43: error: static assertion failed: usage of batch type with unsupported type
   71 |             static_assert(!A::supported() || xsimd::has_simd_register<T, A>::value,
      |                           ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/xsimd/types/xsimd_traits.hpp:71:43: note: ‘((! xsimd::fma3<xsimd::avx2>::supported()) || ((bool)std::integral_constant<bool, false>::value))’ evaluates to false

It would be great if xtensor could be updated for xsimd 12.

We sould probably release xtensor 0.25 first, since no release of xstensor with the upgrade to xsimd 11 has been done yet.

[drew-parsons]

Makes sense to do that first.

xsimd 13 now

Hello from Conan team! We have some conflicts with arrow recipe and we may need to upgrade xsimd/13.0.0 dependency. Any update on this? Thank you!
