Fix promoted assets not being assets in vue (#7576)

- Fixes asset widgets which have been promoted failing to display as
asset widgets and having red names in vue mode.
- Fixes promoted subgraph widgets failing to resolve inputSpec for use
in vue mode.

I'm not excited that this creates further bloat of SimplifiedWidget.

Known issue
- Similar to #7550, subgraph widgets will have an incorrect callback and
will fail to update value on a fresh reload. This can be "fixed" (made
worse) by entering and exiting the subgraph. Since this creates a
'leaked' widget callback which will then be called.
