Bulk edit controls are currently displayed within the search bar of the
list view. This doesn't make sense from a UX perspective, as the current
selection is displayed somewhere else entirely. These controls also take
up a lot of visual real estate which is beginning to get overused
especially after the introduction of "list menu items" in #11230, and
the potential introduction of "saved filters" controls in #11330.
Now, they are rendered contextually _alongside_ the selection count. To
make room for these new controls, they are displayed in plain text and
the entity labels have been removed from the selection count.
