Gregory P. Smith b949033ae8 gh-160535: Keep the ZstdDict alive until the zstd context is freed (GH-160536) ...

The garbage collector could release a ZstdCompressor's dictionary, or
the digested dictionaries cached by the ZstdDict, while worker threads
of the compression context were still reading them.  They are now only
released on deallocation, after the context has been freed.
