Now that we have an explicit syntax for mixins that is available all the time, we have to do mixin inference error checking all the time, not just when the "--supermixin" flag is supplied. This required fixing several minor bugs: - ErrorVerifier._checkForMixinSuperInvokedMembers did not properly handle a mixinElement argument that was a ClassElementHandle. - ErrorVerifier._checkMixinInference wasn't using the actual substituted mixin types, causing errors to be wrongly reported when a class declaration had multiple inferred mixins (this was the root cause of #34404). - Type names in "with" clauses in the resolved AST weren't properly reflecting the mixin type arguments that had been inferred. Fixes #34404.
