Emit metadata for runtime checks of conformances of associated types to invertible protocols, e.g., `T.Assoc: Copyable`. This allows us to correctly handle, e.g., dynamic casting involving conditional conformances that have such constraints. The model we use here is to emit an invertible-protocol constraint that leaves only the specific bit clear in the invertible protocol set. (cherry picked from commit ae01d20)

T.Assoc: Copyable. This allows us to correctly handle, e.g., dynamic casting involving conditional conformances that have such constraints.SuppressedAssociatedTypes)[https://github.com/[6.0🍒] NCGenerics: introduce SuppressedAssociatedTypes #72812]), and only when that's enabled will the runtime change have any effect.
