Fix array_normalize to support int types. (facebookincubator#11173)

Summary:
Pull Request resolved: facebookincubator#11173

Presto java supports array normalize with int type (https://github.com/prestodb/presto/blob/832b071b3c74f65a6fe8386dc296b61f17192a7a/presto-main/src/main/java/com/facebook/presto/operator/scalar/ArrayNormalizeFunction.java#L56-L64). To support similar caess, registering array normalize with int types and extended tests.
