DRAFT: First pass at adding license scan result policy rules behind feature flag

What does this MR do and why?

Adds the first iteration of license scanning result policies behind a feature flag.

Covers the following 2 issues:

#371506 (closed)

#371507 (closed)

Things done in this MR:

• Refactor several Vue components to extract shared logic between license scan policies and security scan polices
• Add 2 versions of configuration behind a feature flag.
• Create a V2 feature flag component so we can more easily toggle between the two.

NOTE: %{licenseType} will be completed as part of #371508 (closed) next milestone
