[SHELL32] Backport, Remove redundant "Line up icons" from desktops context menu

A partial backport of 0.4.14-dev-1506-gc82ba34 (2020-04-20)
That menu item never had any effect up to now as it had no implemention in ros,
and it also does not exist on Windows at this location.
The desired effect can already be achieved by just hitting F5 or selecting "Refresh" from the same root-context menu.

I do port back only the removal of this commit for now, and not the added new functionality in the submenu "Arrange Icons By", to
allow translations for that to settle down a bit on master.

The purpose of the backmerge is streamlining the UI and reducing shell32 binary size a bit.
