stb_image: IDCT kernel func ptr in stbi__jpeg
...
I want to support SSE2 kernels that auto-detect. If implemented
using globals, this would trigger thread race checkers if stb_image
was used in multiple threads. Just make the kernels be explicitly
per-stbi__jpeg to avoid this.
(This commit is the first step in replacing existing STBI_SIMD
functionality.)

Inside decode_block, we're still sparse, and we can use that
sparsity pattern without doing extra work to discover it.
