Gizmo: remove 'Click Anywhere' option

Having an invisible gizmo caused event handling problems (see: T56603).

This is hard to avoid since gizmos are similar to buttons in the way
they have priority over the regular keymap.

Transform events use tweak so events to fall though to the general
view 3d keymap (for cursor placement for eg).
