Explanation: Shared references imported from C++ were not considered safe. This is a widely used feature and this fix is blocking the users from adopting strictly memory safe Swift.
Issue: rdar://151039766
Risk: Low, the fix only changes what declarations are considered safe.
Testing: Regression test added.
Original PR: #82203
