set OCaml default behaivor to enable concurrent dec ref #6160

Browse source 
Add Z3_enable_concurrent_dec_ref to the API.
It is enables behavior of dec_ref functions that are exposed over the API to work with concurrent GC. The API calls to dec_ref are queued and processed in the main thread where context operations take place (in a way that is assumed thread safe as context operations are only allowed to be serialized on one thread at a time).
