d52235f2 - macOS: workaround a dyld/libunwind deadlock issue since 12.1

macOS: workaround a dyld/libunwind deadlock issue since 12.1 Apple reintroduced the old bug that we previously worked around in fad04d39d592d8e0fcbfba439e8157f582bbc850 with a similar patch to this. This is needed anywhere that we may attempt to stop threads. Fixes #43578 (cherry picked from commit 2939272af2ef3fe9d8921f7ed0a6500e31a550c9)
