Rollup merge of rust-lang#151525 - ZuseZ4:update-enzyme-jan-22, r=Kobzol

update enzyme, includes an extra patch to fix MacOS builds in CI

I updated the submodule under rust-lang/enzyme to match EnzymeAD/enzyme, and added one commit, which based on some testing should fix how we build Enzyme in the MacOS CI. Once this pr landed, we will verify again that CI still works, and afterwards upstream the patch and drop it from our fork. No new test failures.
