Rollup merge of #147843 - bjorn3:tidy_licenses, r=clubby789

Change the tidy license checker

This adds a bunch of licenses to the global list of allowed licenses that are at least as permissive as some other license in the list. In addition it adds another list for licenses that are allowed to be used by tools, but not by the runtime. All permissive licenses from the exception lists are added here. This makes it clearer what actual exceptions to our permissive licensing policy are and will hopefully make it a bit easier to review future changes to the list of licenses rather than just adding whatever license is necessary to the global list of allowed licenses or to the list of exceptions.
