Use Interface transactions, not Device transactions, to destroy Interfaces

Summary:
Depends on D19324. Ref T13120. Ref T12414.

This moves "Destroy Interface" to use Interface transactions instead of Device transactions, so we can ultimately get rid of the complex and difficult-to-modernize `AlmanacDeviceTransaction::TYPE_INTERFACE`.

This transaction is a bit weird since it makes the interface delete itself, but this should work OK for now. At some point in the future I'd probably want to change this…
