Add implementation for wasi_thread_spawn() (#1786)

Browse Source 
For now this implementation uses thread manager.

Not sure whether thread manager is needed in that case. In the future there'll be likely another syscall added (for pthread_exit) and for that we might need some kind of thread management - with that in mind, we keep thread manager for now and will refactor this later if needed.
