[C++] Implement union-like data type for accommodating kernel arguments which may be scalars or arrays #1423

Note: This issue was originally created as ARROW-1485. Please see the migration documentation for further details.

Original Issue Description:

For example, either argument to the binary operator Add may be scalar or array. Some systems have addressed this issue by using arrays of length 1, but I would prefer that we accommodate this in Arrow's C++ data types
