eggimagemenubutton: Copy and un-deprecate GtkImageMenuitem

This was deprecated without reference to a bug or reasoning,
and we need it for our importer drop down button. We want
to show the device image in the drop down menu. So copy it
from GTK+, clean it up, and keep using it.

Add a tool to test GcrImportButton

ui: Stop using GtkStock now that it's been deprecated

Use alternative

eggimagemenuitem: Update comments about for GtkImageMenuItem

Reasoning here: https://docs.google.com/document/d/1KCVPoYQBqMbDP11tHPpjW6uaEHrvLUmcDPqKAppCY8o/pub

Although it would be nice to port to GtkMenuButton, doing so would be
breaking ABI, and can't be done until 4.x (likely in sync with GTK+ 4.x)

We still want to continue using icons in our dropdown import button.
So the 'egging' of GtkImageMenuitem still stands.
