[FLINK-5628] [webfrontend] Fix serialization of stats tracker
Instead of exposing the stats tracker in `AccessExecutionGraph`, we expose
the checkpoint stats snapshot. That way, we don't have to worry about
serializibility in the tracker itself. The archived execution graph simply gets
the latest snapshot before archival. With this change, we also prevent illegal
use of the tracker after it has been archived.
Not strictly necessary for 1.2 but nice to have in order to have an easier
time when backporting stuff from 1.3 later.
