Make sure we call the ProcessAssertion invalidation handler on the main thread. BKSProcessAssertion calls our invalidation handler on a background thread which leads to thread safety problems and crashes.

Still need to update the iOS simulator half of ProcessAssertionIOS.mm to use WTF::Function instead of std::function.
