feat(ec2): include resource metadata in Check_Report

[MrCloudSec]

Context

This PR refactors the Check_Report and Check_Report_AWS classes to dynamically handle resource_metadata. For now, the changes are applied only to the EC2 service, allowing EC2-specific details to be included in the data field of the OCSF output. This improves the context of findings for EC2 resources while maintaining flexibility for future expansion to other services.

Description

• Added resource_metadata to Check_Report: Dynamically extracts attributes from the EC2 metadata object and serializes them into a dictionary.
• Updated Check_Report_AWS: Automatically populates resource_id, resource_arn, and region for EC2 findings using resource_metadata.
• Improved OCSF Output: Includes resource_metadata in the data field under metadata, providing enriched context for EC2 findings.
• Initialization Updates: EC2 Check_Report_AWS instances now require resource_metadata as part of their initialization to ensure consistent data handling.
