Remove support for zext and sext constant expressions. All places creating them have been removed beforehand, so this just removes the APIs and uses of these constant expressions in tests. There is some additional cleanup that can be done on top of this, e.g. we can remove the ZExtInst vs ZExtOperator footgun. This is part of https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179.
