Add back option to not adjust output batch size (#19442)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/19442
For cases like CV, some of ops like transpose and tile will mangle the batch size so that we don't know how to adjust output batch size. In this case, the current solution is just fix the input batch statically and do not adjust output batch size.
