Refactor QC Preflight Checks workflow configuration

[sudeeshna21]

Running untrusted code on the pull_request_target trigger may lead to security vulnerabilities. These vulnerabilities include cache poisoning and granting unintended access to write privileges or secrets.

https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows#pull_request_target

We should update all usage of pull_request_target in all workflow files and also update qualcomm-preflight-check to the latest.

What Enabling Code Scanning Means:

• The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
• Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
• You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.
