Generate helper function for C++ to perform operations on backing objects for each observable array attribute, - ElementAt: Get the item at that index. Throw error if fail to get the element. - ReplaceElementAt: Replace the item at the index, this will also trigger OnDelete and OnSet callback. Throw error if fail to replace the element. - AppendElement: Append one element to the end of the array, this will also trigger OnSet callback. Throw error if fail to append the element. - RemoveLastElement: Remove the element at the last index, this will also trigger OnDelete callback. Throw error if fail to remove the element. - Length: Get the number of the indexd value. Throw error if fail to get the length. Depends on D113728 Differential Revision: https://phabricator.services.mozilla.com/D113862
