[OpenBLAS_jll] Update to new build with BFloat16 kernels (JuliaLang#5…
…3059) This also * drops a patch (`deps/patches/neoverse-generic-kernels.patch`) not needed anymore for an [old bug](OpenMathLib/OpenBLAS#2998) fixed upstream in OpenBLAS. This results in ~5x speedup in the computation of `BLAS.nrm2` (and hence `LinearAlgebra.norm` for vectors longer than `LinearAlgebra.NRM2_CUTOFF` (== 32) elements) when the neoversen1 kernels are used, e.g. by default on all Apple Silicon CPUs * adds a regression test for the above bug * updates other patches when building openblas from source Corresponding PR in Yggdrasil: JuliaPackaging/Yggdrasil#7202.
