DataViews list layout: hide actions menu when there is only one action and is primary

[oandregal]

Part of #65165

What?

This PR hides the actions menu for the DataViews list layout when there's only 1 action and is primary.

Before	After

All current core screens have more than one action. See testing instructions below.

Why?

To improve UX.

How?

Testing Instructions

This is something we've heard from extenders. Because there's no place in core where we have this situation just yet, we have to create one for testing:

• Go to the post-list code and remove the postTypeActions in this line and in the line below (in both arrays).
• Visit the Pages page and verify only the edit icon is displayed.

Note this checks actions, not eligibleActions. This is intentional to make sure that we only hide the item menu when all the items has a single action. We wouldn't want to show only the icon for some and the icon + the actions menu for others.

Works as expected ✅

P.S. Nitpick: The Array.filter will always return an array. There's no need for optional chaining on this line.
