Fix Mutate() methods of Array<scalar/struct> (override 5508) (#5526)

Browse Source 
* Draft with Array specialization (#5508)

* Array specialization + SFINAE to fold copy-paste (#5508)

* Add implicit specialization of Array<scalar> and Array<struct> (#5508)

- Tag dispatching is used for implicit specialization
- Array<scalar> and Array<struct> have different iterators and accessors
- Array<scalar> and Array<struct> have different Mutate() methods
