LibGUI: Add Ctrl-U to insert mode
While under insert mode, Ctrl-U deletes all characters between the first non-blank character of the line and the cursor. Implement delete_from_line_start_to_cursor() in TextEditor. Then, call the method in VimEditingEngine via its pointer to an instance of TextEditor.
