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 into more of a "disable" action, but I don't think we face any immediate peril by retaining this behavior for now.
