[v1.x] Docker cache enhancements (#20525)

* Properly initialize set so that docker cache builds exclude the centos7 dockerfile.

* Change the number of parallel builds to 1 for easier debugging and bandwidth control, also parameterize the number of build retries and reduce from 10 to 1 for easier debugging.

* Remove old dockerfiles.

* Update docker-compose config to use new ECR-based naming scheme.

* Refactor build.py and docker_cache.py to support building and pushing containers for the docker-compose based platforms. Add options for selecting architecture (defaults to x86) since aarch64 container builds will fail on x86 systems.

* Remove old commands for building docker-compose based containers since they are not built in docker_cache.py.

* Fix running of docker-compose based containers via build.py.
