knowledge_plugins, code_location: recompute hashes after unpickling (#6511) 
* knowledge_plugins, code_location: recompute hashes after unpickling

Atom, Definition, and CodeLocation cache their hash in a `_hash` slot. The
default pickling persists that slot, but the hash folds in per-process-salted
hashes (e.g. of register-name strings), so a value pickled in one process is
stale when unpickled in another -- equal objects then hash differently, which
breaks sets/dicts (and assertCountEqual) rebuilt from a pickle.

Add `__getstate__`/`__setstate__` that drop `_hash` from the pickled state and
reset it to None on load, so it is recomputed lazily in-process. `__dict__`
and all slots are otherwise preserved, and the existing default-format
pickles still load.
