ARROW-11839: [C++] Use xsimd for generation of accelerated bit-unpacking The custom per-ISA code generation scripts (AVX2, AVX512) are replaced with a single code generation script that outputs xsimd code for any SIMD bit-width, in an ISA-agnostic way. Also add a Neon optimized version of bit-unpacking that leverages the generated code for 128-bit SIMD.

Apache Arrow is a development platform for in-memory analytics. It contains a set of technologies that enable big data systems to process and move data fast.
Major components of the project include:
Arrow is an Apache Software Foundation project. Learn more at arrow.apache.org.
The reference Arrow libraries contain many distinct software components:
The official Arrow libraries in this repository are in different stages of implementing the Arrow format and related features. See our current feature matrix on git master.
