[QNN EP] Repackage Windows artifacts with signed libs

[qti-mbadnara]

This PR makes the change to add the option to repackage the Windows artifacts with the signed DLLs across Wheel, Zip and NuGet as part of the release pipeline. This workflow is triggered as part of .github/workflows/qualcomm-internal-upload-artifactory.yml when the --sign_artifact argument is set as True.

Requirements before running the workflow to repackage the artifacts

• JFROG_API_KEY
• The signed libs uploaded as a zip for the corresponding artifact under the zip-project, (e.g) <VERSION>/signed_libs/wheel.zip

Before reviewing the code, how do you plan to meet the requirement - "The signed libs uploaded as a zip for the corresponding artifact under the zip-test-project: /signed_libs/wheel.zip"?
BTW, the signed_libs should be uploaded to zip-project rather than zip-test-project.

For now the libs need to be uploaded manually to the artifactory, but very soon changes will be made to automate that process, though that will take some time. This change is needed for upcoming releases

Changes were made to publish the signed_libs to aisw-zip-project

LGTM. Do we need to trigger workflow to validate it?

I think it should be fine!
