Implement alpha equivalence proofs (#7066)

This is a modified version of #6137 which accounts for extended rewriting between quantified formulas that are considered alpha equivalent.

It also generalizes the proof rule ALPHA_EQUIV. Notice that if we were to make this rule more pedantic, we would check for variable shadowing during substitution, although this is not currently done.
