feat(batch): add fargate Runtime Platform properties to ECS Fargate C… (#28841)

The property [RuntimePlatform](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-jobdefinition-containerproperties.html#cfn-batch-jobdefinition-containerproperties-runtimeplatform) is not present in the AWS Batch ECS Fargate Job Definition. This PR adds flatten properties fargateCpuArchitecture and fargateOperatingSystemFamily to the ECS Fargate Job Definition in AWS Batch.

Closes #26484.
