next/ci/tf-ci-scripts/misra-docker-images: add support for misra ECR

This change adds in support for automating the build of docker images
related to MISRA.

Dockerfiles are expected to be found in the ci/misra-dockerfiles
repository organized into directories that match the image's tag
name.

Private files are expected to be found in s3 under the dockerfiles/tag
name folder.
