deephaven.ui widgets do not appear in Console dropdowns

[mofojed]

Description

When you create deephaven.ui components, they do not appear under the Console table or widget dropdowns. They're only under the Panels menu.

Steps to reproduce

1. Create a deephaven.ui widget in the console:

from deephaven import ui

foo = ui.text("Bar")

2. Check the table/figure dropdowns in the Console panel

Expected results
2. foo should appear in a dropdown and be openable

Actual results
2. foo does not appear in either dropdown. It only appears under "Panels"

Additional details and attachments
We should consider having one dropdown for all the objects, with a filter in that dropdown for type? The dropdown is redundant of the Panels menu, get rid of it entirely (for Core)?

consider having one dropdown for all the objects (for enterprise)

I support that.

@wusteven815 you should be able to just delete ConsoleMenu, and just pull the "More Actions..." part up into ConsoleStatusBar.

For Enterprise I'll take care of consolidating the dropdown when I convert to use the Core Console Plugin from Enterprise (DH-16756)

Taking this because I'll be refactoring Console/ConsolePlugin with DH-16263 already.

The console dropdown and panels menu have a slight behavior difference in enterprise at least.

Console dropdown -> reopen over existing panel the console opened (DH-16614 is a bug w/ this behavior)
Panels menu -> open new panel w/ the widget

From the panels menu you can open the same widget multiple times. I think it's fine to combine as the difference is not communicated to users, but just wanted to note it
