Mike Conley 32a23a9084 Bug 1801314 - Add initial infrastructure for a migration wizard reusable component. r=Gijs,kpatenio,NeilDeakin,niklas,mstriemer ... This adds: 1. A new <migration-wizard> component 2. A new migration-dialog.html document that loads it 3. JSWindowActors for communicating between whatever process the migration-wizard is loaded in and the parent process. The actors are currently restricted to running in these documents: about:welcome about:preferences chrome://browser/content/migration/migration-dialog.html 4. A very small, simple mochitest-chrome test for testing the widget 5. Some Fluent strings for the new <migration-wizard>, dropped into a new folder in /browser called "locales-preview". This is so that both the jar packaging can put the Fluent file somewhere sensible that doesn't (currently) require our localizers to translate, but also so that Storybook can load that Fluent file. 6. Modifications to our Storybook infrastructure so that attempts to load items from locales-preview will map to the browser/locales-preview folder. 7. A Storybook story for the <migration-wizard> that puts it in a few basic states. Most of those states aren't actually implemented yet, but are left in the story to make it easier to develop those states in the component. The hope is that when this is done, it should be relatively straight-forward to embed the <migration-wizard> not just in the migration-dialog.html document (which is used for tab modals and the stand alone migration dialog), but also in existing in-content pages like about:welcome and about:preferences. For those worried about the TODO strings or incomplete behaviour, remember that this is just a base for building upon, and that this component / dialog isn't actually exposed to users yet. The dialog can be opened manually via: ```lang=js gBrowser.getTabDialogBox(gBrowser.selectedBrowser).open("chrome://browser/content/migration/migration-dialog.html") ``` and see the documentation in browser/components/storybook/README.md for guidance on how to view this component using Storybook.
