[code-reflection] RFR: Add private and local arrayView support

[Ruby Chen]

Private and local arrayViews can now also be accessed using `.privateArrayView()` and `.localArrayView()`, respectively.

Implementation of `.privateArrayView()` and `.localArrayView()` is left to the user, and accessing global arrays is still kept as `.arrayView()`.
