Enable ThreadSanitizer in Darwin CI. (#26614)

* Enable ThreadSanitizer in Darwin CI.

Unfortunately, "-enableAddressSanitizer NO" does not seem to override the
scheme, and you can't do both AddressSanitizer and ThreadSanitizer at once, so
this turns off AddressSanitizer in the scheme and manually enables it in the
command line for the test.

* Fix threading issue the new test caught.
