53609b90 - [analyzer][NFC] Prune a very obsolete comment about CoreEngine (#101173)

[analyzer][NFC] Prune a very obsolete comment about CoreEngine (#101173) Once upon a time, a long time (16 years) ago there were two classes called `GREngineImpl` and `template <class CHECKER> GrEngine`. As the years passed, they were merged into a single class that went through several renames, but this comment still preserved the memory of their old relationship... until now.
