Add mutex stress test (#2472)

As a part of stress-testing we want to ensure that mutex implementation is working
correctly and protecting shared resource to be allocated from other threads when
mutex is locked.

This test covers the most common situations that happen when some program uses
mutexes like locks from various threads, locks from the same thread etc.
