We create threads using std::thread in various places in the test suite. However, the usual std::thread constructor may not work on all platforms, e.g. on platforms where passing a stack size is required to create a thread. This commit introduces a simple indirection that makes it easier to tweak how threads are created inside the test suite on various platforms. Note that tests that are purposefully calling std::thread's constructor directly (e.g. because that is what they're testing) were not modified.
