[TSan][Apple] Fix interceptor build error (#124351)
In certain cases, the SDK headers declare
`OSSpinLock*` APIs as macros (instead of
functions), so users can be transparently
forwarded to non-deprecated APIs.
When enabled, building of TSan interceptors failed
because these macros interfere with the
interceptor machinery, i.e., they prevent proper
forward declaration of intercepted APIs.
In a previous change [1], we misattributed this to
the deprecation of `OSSpinLock*` APIs.
