Pavel Yaskevich f650c0ac6e [CSBindings] Prevent BindingSet::isViable from dropping viable bindings (v2) ...

The original attempt to do this was reverted by https://github.com/swiftlang/swift/pull/77653

The problem is that the fix was too broad, I narrowed it down to
non-exact uses of stdlib collections that support upcasts.

(cherry picked from commit b7e7493076)
