Add generate script option to DacFx wizard (#3789)

* Add generate script option to deploy scenario

* add action to summary page and fixed page adding/removing so that summary page will have the correct step number

* updating contract based on change in sqltoolsservice

* added enums to make index checks more clear

* cleaned up onPageChanged()

* bump sqltoolsservice version to 68
