Fix retry_on handling in run_with_retry
...
- Correctly distinguish between exception classes, lists/tuples of exception classes, and callables.
- Add support for lists in `retry_on`, alongside tuples.
- Prevent exception classes from being incorrectly treated as callables.
- Raise a `TypeError` if `retry_on` is of an unsupported type.

Support lists in retry_on for RetryPolicy
...
Previously, `retry_on` in `RetryPolicy` accepted only exception classes, tuples of exception classes, or callables.
Update the `retry_on` type annotation to include `List[Type[Exception]]`
Changes:
- Updated `retry_on` in `RetryPolicy` to accept `List[Type[Exception]]`.

More performance improvements in checkpointing and channels ( #1685 )
...
* Performance improvements in checkpointer libs
- Use sha1 instead of md5 for hashing (faster in python 3.x)
- Use orjson instead of json for json dumping (sadly can't use for json loading)
* Update tests
* Update
* Use random number instead of hash for get_version_number
* Avoid saving writes for the last task to complete in each step
- only when possible, exceptions for ERROR, INTERRUPT, SEND
* Make Channel.from_checkpoint a regular function
- context manager no longer needed since Context became a managed value
* Use __slots__ for Channels
* Fix for kafka
