scanner: Flatten multi-dimensional arrays fields

Provide partial support for multi-dimensional arrays by representing
them as flattened one dimensional array with size that is equal to
product of sizes in each dimension. Previously only the first dimension
would be actually used.

This should be sufficient to ensure that those fields have layout
compatible with C, without using nested array types that are currently
unsupported by vapigen

Issue #255.
