Migrate CE MrWidgetOptions spec to @vue/test-utils
What does this MR do?
This is a mostly-straight-forward and nearly minimal migration; there are a lot of issues with the existing suite, e.g., mutating props directly; making assertions against component internals; inconsistent use of async/done/promise chains. Fixing these problems is well outside the scope of this, and can be addressed later.
Partly addresses #220476.
