Vendored analyzers/report/v3 dependency

What does this MR do?

• Introduces analyzers/report with all the dependencies that are required by trivy-k8s-wrapper and the gitlab agent.

Why are we doing this?

We want to reduce the number of dependencies introduced by the trivy-k8s-wrapper when we introduce it as a dependency in the Gitlab-Agent. We. have measured that by removing gitlab.com/gitlab-org/security-products/analyzers/report/v3 and vendoring the parts that are required in the codebase we reduce the number of dependencies introduced significantly.
