Graviton arm-based support for Agones Components

[zachs-1]

Description of changes: Check the CHANGELOG_README.md for more details on changes. All changes in the file would be added to the main branch. Some of the main changes are as follows:

• Wrapped up all SuperTuxKart changes so it now works with Arm-based instances. Running the game with AI racers has not been tested yet.
• Modified ncat gameservers to have the ability to run with arm-based containers. Made ECR repos mutable. Added arm-arch node affinity to /integration/director/director.yaml and /integration/matchfunction/matchfunction.yaml.
• Improved the readability of the terraform/cluster section of the README.md file. Improved the markdown formatting of the CHANGELOG_README.md file. Removed functionality for deploying arm-based nodes for openmatch. Fluentbit now creates whatever CloudWatch Log Groups it needs upon deployment. Fixed the README.md file's instructions for fetching the load balancer arn.
• Added more flexibility for choosing which Managed Node Groups (MNGs) can have which architecture. The deployer can have 1, all, none, or any number in between of MNGs using an arm-based architecture. The deployer can also specify which MNG in which cluster should have which architecture type.
• Pass in a boolean option when creating the core cluster in the CLI to switch between x86-based and arm-based instances in the cluster's Managed Node Group. The deployer is responsible for ensuring that the non-default instance types in the terraform variables files have the architecture that matches the expectation of the array they are in.

If there are any files where Amazon's copyright message needs to be displayed at the top then I can go ahead and make the necessary changes.

I reviewed all the changes and they look good. We just need to solve the merge conflict in the matchfunction Dockerfile and it should be fine.
