This PR creates auxiliary theorems for congruence proofs generated by simp. Some of them can be big are created over and over again in each simp invocation.

It doesn't work. Suppose f is of the form C.{t_1, ..., t_n} where t_is are the universe arguments. then mkCongrSimpCore? f is not equivalent to f.congr_simp.{t_1, ..., t_n}. The problem is that f.congr_simp is computed with abstract universe levels.
