add 6th gen general purpose instance stores

[nimeshjm]

The general purpose (e.g., m6id) instances with local disks map vcap/data to the 10GB ephemeral instead of the local SSD, leaving it unused. This PR aims to mount vcap/data to the local storage SSD for the following vm types: m6id, m6idn, c6id, r6id, r6idn https://aws.amazon.com/about-aws/whats-new/2022/05/introducing-amazon-ec2-m6id-instances/ https://aws.amazon.com/about-aws/whats-new/2022/05/introducing-amazon-ec2-c6id-instances/ https://aws.amazon.com/blogs/aws/new-amazon-ec2-r6id-instances/
