process_replay: universal replay mechanism using cereal fake sockets (#28115)

* replay_process_with_fake_sockets implementation

* add missing polled_pubs to configs

* drained_pubs field

* updated cereal

* Remove python/native variations of process replay. Replace with universal one using cereal fake sockets

* Replace old py FakeSocket with DummySocket

* Invalidate and deregister fake sockets after replay is done

* Remove unused import

* Set up new prefix for each replay

* Fixes for radard

* Refactor ReplayContext and ProcessConfig

* Minor fixes

* Reimplement controlsd fingerprinting callback

* time.sleep for sockets to safely reconnect

* Fix fingerprinting for controlsd

* Fixes for regen to work

* Fix replay loop to respect submaster frames

* Fix profiler to use new ProcessConfig fields

* Remove tqdm

* Refactor tests to use new ProcessConfig

* Add FrequencyBasedRcvCallback

* Make tolerance None by default

* Update cereal

* Add get_process_config utility func

* Update cereal. Simplify sync procedure

* Chain context managers

* New sub-socket reconnection procedure

* Fix linter issues

* Revert chaining of context managers

* Init controlsState only when replaying controlsd. Update cereal

* Update cereal

* Update process_replay to use new cereal API

* Update cereal

* Update cereal

* Update cereal

* Simplify radard recv callback

* Update release/files_common
