This is iterating on how `Destroy.Op` generates, to start adding body capabilities. This changes the way the signature is created, and adds a `CoreWitness` function kind so that mangling can prevent name collisions. The result is that what _was_ `DestroyOp` is now `Core.Destroy.Op` or, as can be seen in toolchain/lower/testdata/interop/cpp/nullptr.carbon, `_COp.<hash>:core.Destroy.Core` where `:core` is indicating that it's a core witness (taking a note from `:thunk`).
