This PR updates c-blosc2 to v2.11.1 which adds AVX512 bitshuffle implementation.

This still need some update/test to enable AVX512 support.

Ready for review.

This compiles blosc2 with AVX512 support if enabled: The SHUFFLE_AVX512_ENABLE is always set and bitshuffle-avx512.c always compiled and the selection of whether or not AVX512 support is available relies on AVX512 compiler arguments (-mavx512f -mavx512bw /arch:AVX512) and #if defined(__AVX512F__) && defined (__AVX512BW__) in bitshuffle-avx512.c.
