Ability to create Global widgets for a Dashboard

In some cases, it would be nice to be able to only allow an admin to create a dashboard widget and make that dashboard widget visible to the dashboard of every user or every user in a group.

Take for example a widget that is has a list of common links that you wish to make available to all content editors. Or a widget about recent sales that you want to make available to all people on your sales team without having them each create and manage changes to the widget individually

This would also work nicely with custom plugin dashboards where a plugin wanted to share common information with all users of the plugin but where users may also want to customize related, less-common information for their particular roles.

No files, tests, or entry points are named. Start by reviewing the related issues, especially #856, #2780, #3361, and #1198, then inspect the dashboard and widget permission flows. Done should include admin-created widgets shared with all users or a group while preserving user customization for other widgets.
