Description

I find NEON code is always skipped by archery benchmark ... even if run on Arm machines.

It's because ARROW_SIMD_LEVEL is fixed to SSE4_2 in archery:
https://github.com/apache/arrow/blob/master/dev/archery/archery/lang/cpp.py#L245

We should use "DEFAULT" simd level which is added in a recent pr to address different archs.
