Add menu item order control (#12362)
Add four new optional properties to menus in Electron. The four properties are:
'before'
'after'
'beforeGroupContaining'
'afterGroupContaining'

'before/after' - provides a means for a single context menu item to declare its placement relative to another context menu item. These also imply that menu item in question should be placed in the same “group” as the item.

'beforeGroupContaining/afterGroupContaining - provides a means for a single menu item to declare the placement of its containing group, relative to the containing group of the specified item.
