Review comment:
How about calling a single function `ValidateAscii` at caller side?
Then, the function calls simd or non-simd function based on ifdef. It makes
code simple by reducing the number of the repetition `#if
defined(ARROW_HAVE_NEON) || defined(ARROW_HAVE_SSE4_2) ...`.
[Here](https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/byte_stream_split.h#L614-L622)
is an example.
