libshiboken: Add Array converters

Add a SbkArrayConverter struct which provides a list of
check functions that return a converter function
for an array of matching size.

Add simple array converters for arrays of C++ primitive types.

Instances of the ArrayHandle<>,  Array2Handle<> templates will be
generated which may point to internal data or allocated arrays.
