Use quickpick with search and toggles to toggle the setting value per language

<!-- ⚠️⚠️ Do Not Delete This! feature_request_template ⚠️⚠️ --> <!-- Please read our Rules of Conduct: https://opensource.microsoft.com/codeofconduct/ --> <!-- Please search existing issues to avoid creating duplicates. --> <!-- Describe the feature you'd like. --> The current Modified Elsewhere hover doesn't make it easy to quickly identify what value per language is set to, is it possible to instead use a quickpick with toggles per language showing the value for the setting. In this example, global formatOnSave is enabled, with some languages having default or user-set overrides to false. The dialog then shows the languages with the overrides and you can toggle from the quickpick or search for a language. <img width="808" alt="image" src="https://user-images.githubusercontent.com/13228044/204051091-0454a4ab-1804-472e-907b-eb7e79235cd8.png">
