1803677 - Expand options for using the `./mach addwidget` scaffold command

Status: NEW

(Toolkit :: UI Widgets, enhancement)

Description

[Hanna Jones [:hjones]]

Currently the ./mach addwidget command assumes we want to create our reusable components using Lit and that we want to add them to toolkit/widgets. Already we've run into a couple of cases where people want to create vanilla custom elements and/or create reusable components that live in a different directory. We could make the scaffold command more flexible by having it accept args like --path and --no-lit. This will help make it easier to create more different kinds of components while ensuring they still get documented in Storybook.
