[BE] Remove Model Dump utility (pytorch#141540)

So I found this utility by accident, trying to find how many html files we have in the repo so I could convert them to markdown

Turns out we package some html and js files in pytorch to visualize torchscript models. This seems kinda strange, probably shouldn't be in core, I removed the tests I could find. Maybe some internal tests will break but considering torchscript is being superseded might make sense to do this

Last time there was a meaningful update to the test for this file was about 2 years ago by @digantdesai since then it's a bunch of routine upgrades

It seems like this package is unused https://github.com/search?type=code&auto_enroll=true&q=torch.utils.model_dump&p=1 I skimmed through 5 pages of these and the only time this shows up in code search is when someone is either cloning pytorch or checking in their venv into github
