Adds a new optional `CodeActionProviderMetadata`. This is passed in`registerCodeActionProvider` and contains a list of`CodeActionKinds` that the provider may return. The list is used for deciding when to show the `refactor` and `source action` context menus. It is not used for filtering the returned code actions
