Show the folder path a file is in, in title of the window

[vedipen]

Closes #66660

• Adds options in the User Settings > Window: Title for showing the folder path a file is in.
• Simplified descriptions for variables

Added variables -

• ${activeFolderShort}: the name of the folder the file is contained in
• ${activeFolderMedium}: the path of the folder the file is contained in, relative to the workspace folder
• ${activeFolderLong}: the full path of the folder the file is contained in

Resulting view

@vedipen I am not a big fan of the logic in titlebarPart.ts to get the labels for short, medium and long folder. You implicitly assume that the label you get from the input is already a path, but that might not be true. A better solution imho would be to get the resource from the input and then do what the fileEditorInput does, e.g. here https://github.com/Microsoft/vscode/blob/cfd5d35/src/vs/workbench/parts/files/common/editors/fileEditorInput.ts#L171

@bpasero Thanks for the feedback. Updated the logic.

@vedipen I think we can still improve this a bit, specifically I think we do not need to check for file scheme but can try to support this for any resource. This would help in cases where the user opens remote resources which are not local.

As such I suggest:

• continue to use the toResource(editor, { supportSideBySide: true }) but remove the check for file scheme
• use resources.dirname() instead of paths.dirname() which takes care of resources
• pass that into this.labelService.getUriLabel as before
• use resources.basename instead of paths.basename for the short label

@bpasero Is this ideal or should we add a function for getting these paths (or maybe use getDescription)?

Thanks I think its fine. I will push small tweaks after to clean up a bit.
