Add support for XFS as a filesystem

[yeazelm]

What I'd like:
The XFS filesystem can improve performance in some workloads or use cases and it would be great to support this in Bottlerocket for the data partition.

This would involve having a flag to enable XFS on a particular build and then ensuring tools like xfsprogs is available on the OS for managing things like expanding the filesystem using xfs_growpart.

Any alternatives you've considered:
Other filesystems could offer support but would involve similar work to enable. Nonetheless, there are times where using something other than ext4 would be beneficial.

#3198 adds xfsprogs to Bottlerocket images as well as switch the BOTTLEROCKET-DATA partition to XFS for -dev variants.

XFS support was merged in with #3198. Right now its only -dev variants that have it enabled via the image-features setting xfs-data-partition = true.
