c2ab31113f refactor(library/tactic): remove cex_builder and 'precision' for proof_state's
These two features make sense for solvers, but not in a general purpose tactic framework for building proofs like the one in Lean.

In most cases, we cannot build a counterexample anyway. These two features should be added in a custom framework for combining preprocessing techniques like in Z3.
