Refactor ANTLR message simplification infrastructure.

Browse Source 
Refactor ANTLR message simplification infrastructure to reduce class count within preproc given @benfy feedback within https://github.com/processing/processing4/pull/1. Note that some supporting are left out but those can be further refactored behind classes as desired but strategies are all made anon or inner.
