Do not trigger runs when dependency changes

In the Stack dependencies setup, there is the option to always trigger when a dependent stack runs, or only when the specific dependency changes, but not to not trigger a run in any case.

As stack dependencies are the recommended way of using outputs from other stacks, it would be great to have another mode when an output dependency changes foes not trigger any run.

This shoudl, be doable via the Terraform resource spacelift_stack_dependency_reference

e.g.

• stackA depends on outputX of stackB.

• stackA does not need to immediately do a run when outputX changes

• stackA ← outputB dependency should be able to be configure as “Never Trigger", in the same manner ti an be confgiure with "Always trigger"
