[feature] Add Rename action under the manage submenu for files in bro…

…wser Allows renaming of files directly in the browser. If the file corresponds to a spatial dataset with multiple sidecar files then these will all be renamed accordingly too. Additionally, users are warned if the file is a layer which is exists in the current project and are asked whether they want to automatically update all the layer paths accordingly. Refs #14611
