v2.12.0 WIP

[mgorny]

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Let's see if this fares any better than 2.11.0.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.
• ℹ️ top-level output overrides versions pinned in the feedstock:
  ['- In section host: python 3.12, numpy *']
  Requirement spec should not list version specifiers to respect conda-forge-pinning. If you need to force another version, please override the pin via conda_build_config.yaml.

Ok, this is looking really horrible.

Easy parts:

• missing cub dependency for CUDA
• missing onednn for Linux (osx?)

Hard parts:

• it's trying to compile x86 cpuid code on aarch64
• some -march=core2 failing on macOS
• it fails to find MKL suddenly
• ton of test failures on osx-arm64
