opentofu/terraform resources for secure bootable images on AWS

[yeoldegrove]

What would you like to be added:

We need changes to the upstream terraform provider for AWS to enable secure bootable images that let us bring our own secure boot config and keys.

Why is this needed:

I identified potential blockers to go forward with the openTofu implementation of our secure boot use cases.

• uefi_data needs to be passed to the AMI
• Register Image API
• Terrform AMI resource

The terrafom aws_ami resource cannot define uefi_data at the moment.

• This could potentially be implemented (assessment needed).
• This could be potentially be worked around by patching the AMI later (assessment needed).
