Create a global Dependency Scanning variable to allow file-only fast scans vs built longer scans

Release notes

Problem to solve

Per discussions in this issue #321081 (closed) We would like to make available to users a variable to set all dependency scanning to build / be more precise with the scan. This will take a longer time period and more resources and as such should not be the default but something users choose.

User experience goal

Proposal

Further details

we need to discuss the implication if they mix mode scan in one project (a weekly more detailed vs a per MR fast)

What does success look like, and how can we measure that?

What is the type of buyer?

Is this a cross-stage feature?
