opencascade is just on Mojave, and it's been failing tests there for a while now.

Rebased to pull in some more fixes (e.g. cash-cli deprecated in #75709), plus the ARM runner crashed for some reason anyway.

Mojave:

Other nodes look similar, sans the bottle failure. Other than the bottle failure I'd say this would've been good to merge.

llvm@11: #76030

Failures look nearly identical to #76174, so I doubt they're caused by the version bump. Merging.
