kernel/arm64: fixed cscal and zscal

* Fix ARMV9SME target and add support_sme1 code for MacOS
* make sgemm_direct unconditionally available on all arm64
* build a (dummy) sgemm_direct kernel on all arm64





* Update dynamic_arm64.c

Add vector registers to clobber list to prevent compiler optimization.

Use SVE kernel for S/DGEMVN for SVE machines

Improve performance for SGEMVN on NEONVERSEN1

Further performance improvements to non-transposed [SD]GEMV kernels for A64FX and Neoverse V1.

SME based SGEMMDIRECT kernel uses the vector registers (z) and adding
    clobber list informs compiler not to optimize these registers.

Optimize aarch64 sgemm_ncopy

replace customize bf16_to_fp32 with arm neon vcvtah_f32_bf16

Optimize gemv_n_sve kernel

Add dispatch of SBGEMVNKERNEL for NEOVERSEN2 and NEOVERSEV2

This improves performance for sbgemv_t by up to 100x on NEOVERSEV1.
The geometric mean speedup is ~61x for M=N=[2,512].

* Added ARMV9SME target
* Added SGEMM_DIRECT kernel based on SME1

* Protect align directives in assembly files that are currently problematic with LLVM on WoA

* use the armv8 zdot on WoA to work around other LLVM issues
