Fake Tensor For (Conv) Propagation (#87641)
Resubmitting https://github.com/pytorch/pytorch/pull/87302 so it can be ghstack'd with the pr below.
Incorrect strides in any meta impl would lead to runtime assertion errors for fallback kernels, so start by just enabling it for conv.
Replaces https://github.com/pytorch/pytorch/pull/87588.
