Language option missing from menu link options for layouts

[jenlampton]

Description of the bug

The layouts Menu UI does not provide an option for defining a language for the menu item. Once the menu item is created (via layouts) you need to use the menu UI to set the language, but that will cause the menu link provided by Layouts to be overridden.

Once a menu link is overridden, changes made in the Layout UI (like changing the Menu Link Title) will not be respected.

Steps To Reproduce

1. Enable Locale module and add at least 1 additional language (example: Spanish)

3. From the layouts UI, click the menu settings button for the test layout
   a. Add a normal menu entry
   b. Set the title to test one
   c. Save
4. Visit the Menu UI and change the language for this link to Spanish
5. From the layouts UI, click the menu settings button for the test layout again
   a. Change the menu link title to test two
   b. Save
6. Visit any page and review the menu link
