Rollup merge of #133208 - ferrocene:split-copyright-html, r=Kobzol
generate-copyright: Now generates a library file too. We only run reuse once, so the output has to be filtered to find only the files that are relevant to the library tree. Outputs COPYRIGHT.html and COPYRIGHT-library.html. The license-metadata.json file is also now in the tree. We need a CI tool to check that it's correct. r? kobzol Remaining steps: * [ ] Teach CI to double-check the license-metadata.json file is correct * [ ] Add the COPYRIGHT.html and COPYRIGHT-license.html to the releases
