Generalize inequality elimination in quantifiers rewriter (#7030)
This generalizes our inequality elimination technique to handle disequalities as well as inequalities.
#6999 is an example where a variable can be eliminated: if a variable x occurs only in an equality with negative required polarity, then the variable and that literal can be eliminated.
Fixes #6999.
