* feat(ct): add constructors to interfaces

Adds a pseudo-constructor function called __constructor__ that
will be verified as part of the interface. This pseudo-function
is useful when we want to be able to maintain type safety
in the deploy script where we use vm.getCode.

* add a pseudo-constructor for all remaining contracts with constructors

* fix warning

* update check-interface.sh comment
