Add the ability to override the default behavior of Cloudpickle by passing a CloudPickleConfig to cloudpickle.dumps.

The goal is to maintain default behavior, but add flexibility when different behavior is desired for example foregoing isinstance semantics for deterministic pickling of dynamic types.

This was copied from my cloudpickle fork https://github.com/claudevdm/cloudpickle/tree/cloudpickle-configurable, where I added unit test coverage for a bunch of different configurations and modified tests where appropriate.

I ran internal presubmit and tap for these changes and no issues found.

This is a prerequisite to relaxing dill pickler strict dependency #21298.
