[C++] Add RecordBatch::Validate method that at least checks that schema matches the array metadata

[asfimport]

If the data type in a schema does not match the array type() metadata, this passes unchecked. It would be useful to have a function that can check for this, and for this to run automatically in debug builds (i.e. inside a DCHECK)

It would be good to do this in the RecordBatch ctor in debug builds to prevent common errors
