macOS: Enable crash reporting for tests via Swift

Swift 5.9 includes built in crash reporting, printing stack traces,
libraries, and registers to stdout/err.

https://www.swift.org/blog/swift-5.9-backtraces/

As (Core)Foundation is written in Swift nowadays, we get this feature
for free even in our "C++" apps, as we always link to CoreFoundation.

To enable the feature the binary needs the com.apple.security.get-task-allow
entitlement, so we add it for all our tests automatically.

The final piece is to run the tests with SWIFT_BACKTRACE=enable=yes,
but we'll do this in our CI provisioning, as setting it from within
testlib doesn't seem to work.

Pick-to: 6.8
