Optimize gatherMixinSupertypeConstraints for new mixin syntax.

Since this method is only used to find supertype constraints that are
relevant for mixin inference, it can save its caller from doing extra
work by filtering out mixins that don't take type parameters.
Previously, we were doing that when supporting the old "--supermixin"
feature, but not when using the new mixin syntax.

The method has been renamed to
gatherMixinSupertypeConstraintsForInference so that it's less
surprising that it doesn't return *all* supertype constraints.
