This change partially implements [PR #7362], which revises how objects are destroyed. It is a partial implementation for two reasons: 1. This change moves `Destroy.Op`'s current behaviour into `Destroy.SubobjectDestroy`, but it doesn't add support for objects with non-trivial destruction. 2. `Destroy.SubobjectDestroy` is a workaround for `require impls SubobjectDestroy`. We aren't able to use the latter until the dependents add their requirements' implementations to their own witness tables. [PR #7362]: https://github.com/carbon-language/carbon-lang/pulls/7362
