UI: 3D View, undo menu reorganization

Changes from D2876 by @meta-androcto /w own edits

Move 3x undo items into Undo menu,
these are such common operations they're typically accessed by keys.

Also add to menus which didn't have undo
(seemed random which modes had undo, undo history in their menus).
