[Enhancement]: Add primary IPv6 support to network_interface resource

[miyurusankalpa]

Description

Enable primary IPv6 on network interface. This is option is required to deploy dual stacked global accelerators with ec2 instances as endpoints.

EC2 instances can be added as dual-stack endpoints. However, the instances must have a primary IPv6 elastic network interface (ENI) attached to them. For more information, see Work with network interfaces in the Amazon Elastic Compute Cloud User Guide.
