feat(cloudfront): Ensure Cloudfront distributions have origin failover configured

[HugoPBrito]

Context

This check ensures that Amazon CloudFront distributions have origin failover configured to enhance availability. This PR uses code from PR-4867.

Description

The check verifies that CloudFront distributions use an origin group with multiple origins (2 at least). Origin failover helps maintain high availability by redirecting traffic to a secondary origin if the primary origin fails.

Checklist

• Are there new checks included in this PR? Yes
  • If so, do we need to update permissions for the provider? I do not think so
• [x] Review if the code is being covered by tests.
• [x] Review if code is being documented following this specification https://github.com/google/styleguide/blob/gh-pages/pyguide.md#38-comments-and-docstrings

After conducting a more extensive research, I discovered that while CloudFront distributions can have more than two origins, only two can be configured simultaneously. The new logic leverages this restriction to set a boolean, resulting in a more streamlined, simple, yet effective service structure and check logic.
