[Frontend] Handle filters logic in the Vulnerability Report Filtered Search Component

Summary

The ee/app/assets/javascripts/security_dashboard/components/shared/filtered_search/vulnerability_report_filtered_search.vue component currently does not have any logic to handle filters. It's just a presentational component.

We need to receive the selected filters from the child tokens and pass them to the Vulnerability Report.

Verification steps

• Go to https://gitlab.com/gitlab-org/govern/threat-insights-demos/verification-projects/verify-epic-3429/-/security/vulnerability_report
• Play with the filters and verify the vulnerability report is being filtered correctly
• Make sure the filters are persisted through URL changes
