Build: Enable long term caching for frontend assets (#47625)
* build(webpack): move CopyUniconsPlugin into own file

* chore(webpack): delete unused blobUrl and compile loaders

* build(webpack): prefer contenthash over fullhash for longer caching

* build(webpack): set optimization.moduleIds named only in dev

* build(webpack): introduce HTMLWebpackCSSChunks so templates can access theme css by name

* feat: inject css files with contenthash in html templates

* revert(error-template): remove ContentDeliveryURL from CSS href

* refactor(index-template): update grafanaBootData.themePaths

* chore(webpack): add typescript annotations for CopyUniconsPlugin
