Orchestrator should assign PermissionSetLicenses in validating and deployment of source packages

[azlam-abdulsalam]

sfdx-project.json schema has introduce ability to assign PermissionSetLicenses to the user triggering the test while validating unlocked packages (build)

This reduces the amount of code that needs to be added to individual tests to assign PermissionTestLicenses. sfpowerscripts should implement this during validate, so that its consistent. The same mechanism can be applied for org-dependent unlocked and source packages as well.
