editor.action.focusNextCursor doesn't reveal the primary cursor

[akbyrd]

Type: Bug

editor.action.focusNextCursor and editor.action.focusPreviousCursor do not reveal the primary cursor.

Steps to Repro:

• Create multiple cursors that don't all fit on the screen at once
• Execute editor.action.focusNextCursor
• Notice the editor never scrolls to review a new cursor, indicating the primary cursor is not being revealed

In this gif I've added color to the primary cursor. You can see the primary cursor change both by the color of the cursors both in the editor and the overview ruler. As the primary cursor changes the view does not update to reveal it.

To maximize the usefulness of this command it's helpful if it ensures the primary cursor is visible when it changes. This dovetails nicely with #85630 which has an open PR.
