Edit content mode (select mode): Ellipsis menu button in list view is empty

[andrewserong]

Description

Following #65204, blocks in the list view still show an ellipsis menu, and it's clickable, however the menu is empty.

In this case, where the menu will be empty, shall we skip the ellipsis menu button from rendering?

Step-by-step reproduction instructions

1. Open the site editor
2. At the top left, click the pointer icon and switch from Design mode to Edit mode (formerly known as Select mode)
3. Open the list view, and see that there is still an ellipsis menu button for each item in the list view
