Fix YAML to RULE mode - Filter out rule types

What does this MR do and why?

Fixes switching between YAML mode to RULE mode

Differences in to look out for in screenshots:

• Screenshots of YAML mode are the same
• The bug was toggling back to RULE mode, where it would be disabled with a blue banner above.
• The fix was to only run validations that were valid for security scans by filtering out license scans for those validations.
• We also filter out a empty config from security scan policy validations

How to set up and validate locally

• In a rails console enable Feature.enable(:license_scanning_policies)
• As a EE user Navigate to http://gdk.test:3000/<group>/<project>/-/security/policies
• Or via the nav on the left Security & Compliance -> Policies then New Policies Button then Select Policy in the Scan Result card
• Click New Policy button
• On the Scan Result Policy card click Select policy
• Add a security scan rule without changing any values
• Toggle between RULE mode and YAML mode
• Refresh the page
• Add a license scan rule without changing any values
• Toggle between RULE mode and YAML mode
• Add some values to each rule type
