Right now, the class destroy impl is incorrectly generated (first discussed [in Discord](https://discord.com/channels/655572317891461132/941071822756143115/1418614787449032826)). If we want it to be correct, deferred definition logic would need to be added, and the declaration would need to be moved inside the `class` scope (along with whatever generic logic that needs). This instead switches to a blanket impl, to avoid creating latent bugs with generating the `impl` and function body in the wrong scope. This approach uses the same blanket impl as aggregate destruction that was added by #6098. The intent here is to allow progress on other parts of `Destroy`. For example, under this model the implementation of the function body could be done as part of lowering the specific.
