feat(dev-infra): create format tool in @angular/dev-infra-private (#36726)

Previously we used gulp to run our formatter, currently clang-format,
across our repository.  This new tool within ng-dev allows us to
migrate away from our gulp based solution as our gulp solution had
issue with memory pressure and would cause OOM errors with too large
of change sets.
