Christopher Di Bella 05a7ecbd34 Move SubobjectDestroy and SelfDestruct out of interface Destroy (#7942) 
Determining that a type has trivial destruction requires checking
whether all of its subobjects have trivial destruction and whether its
type has a custom witness for `Destroy.Op`. This isn't possible when
`Destroy` is the custodian for `Destroy.Op` and `SubobjectDestroy.Op`,
so we need to make `SubobjectDestroy` its own interface.

`Destroy.SelfDestruct` becomes a standalone function because it depends
on `SubobjectDestroy` and `Destroy` being implemented, and is also
responsible for generating any custom witnesses for both interfaces.
Making `SelfDestruct` an interface was experimented with, but this
required a blanket impl that caused issues for facet types.

`Destroy` depends on `SubobjectDestroy` to be implemented. We'd ideally
use `require impls SubobjectDestroy`, but it isn't complete yet, and it
also causes problems when `Destroy` is implemented inside the class
definition. We work around this by temporarily renaming the `Destroy`
interface to `DestroyImpl`, and introducing a constraint called
`Destroy` so that user code doesn't need to write `Core.SubobjectDestroy
& Core.Destroy`.
