Elior Nataf LackritzandGitHub 93f5eaff21 fix(checkpoint): keep serialized data when an object can't be rebuilt (#9251) ...

Fixes #6970

If a checkpointed object can't be rebuilt on load (its module was
removed or renamed, or its constructor now rejects the stored fields),
`JsonPlusSerializer` returned `None` for it, so the value silently
disappeared from restored state. The constructor and method ext codes
now return the serialized payload instead, the same thing the pydantic
and blocked-type paths already do, and log a one-time warning per type.
The warning names the exception type only, since exception messages can
echo the stored value.

Thanks @yangbaechu for the report and repro. This takes the same
direction as #6972 by @pandego and #7152 by @SinzoL.
